I am not good to make some advance algorithms (coding questions) as I was not 100% software developer, but I listened to peoples needs and coded for past 20 years to solve/improve problems.
Seeking project/freelance work where I can use knowledge to get you started.
Very rarely they would, I believe. There are thousand of applicants for each job posted. Why would a hiring manager go through a hackernews post unless the skills required are very niche.
I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, copywriting, and I can assist with frontend development where needed. My background of launching my own products and being a full stack developer helps me create practical designs that balance usability, aesthetics, development effort, and performance. I work to fixed price quotes for self-contained projects.

Technologies: Full stack web dev for 15+ years in many forms, and many years of project and product management work, which is more what I'm looking for now. In recent years I've been focused on game development projects using Babylon/WebGL and working with C++ & Go server-side (MMO servers).
I have some cool projects! See my personal site for email and some of those projects:
My most popular project is https://www.idlequest.net/, which is an idle-game web-based version of classic EverQuest, complete with its original 3D graphics. It's basically the entire original EverQuest client recreated to run in a browser, but also has the option to play itself. Also made a new, custom MMO server in Go for it.
Looking mostly project/product management style work. I spent 10+ hours a day working on my own coding projects, which I'm proud of and think are really cool, but I think I'm a little too removed from the nitty gritty coding details these days to be a good IC candidate for a lot of places.
SEEKING WORK | Data scientist consultant | Canada/Remote Worldwide
Most of what people call "data science" is now doable with an LLM and a weekend. I focus on the messy, ambiguous, regulation-heavy gnarly problems where nobody is sure what the right question is. Often it involves getting hands on to find the data and signal that's really needed.
What I've done:
- AI verification of building and architectural BIM/CAD against 400 page ESG standards. (Days of work down to minutes)
- Part failure prediciton, saving a German automaker from lemon law recalls. ($20M+ exposure avoided)
- Oil & gas well and lease production forecasting.
- Real-time emissions detection for industrial smokestacks. ($75K fines per incident prevented)
- Revenue optimization and persona identification for debt collections (15-20% net revenue lift)
- LLM-based legal document extraction, reducing due diligence turnaround from 3 days to 30 minutes
- Built vessel piracy risk engine that informed naval escort deployment, contributing to fewer hijackings
Technologies: Rust, Python, Go · LLM/agent systems, multi-agent orchestration, LLM eval · browser automation + anti-detection (CDP) · data pipelines · dev tooling
Senior engineer & founder, 12+ years. Last ~2 years deep on Rust + LLM agents:
- Built a Rust CDP / browser-automation driver from scratch (anti-detection, agentic pipelines).
- Multi-agent orchestration + an LLM judge/eval layer - claim-level extraction and verification against ground truth — for my own AI SaaS.
- Built AI harness orchestrating different agents in their own native harnesses (agent-to-agent comms, clean room reviews, sandboxing)
- Wrote an architectural linter enforcing pure/effectful separation in large Rust codebases.
Before founding: Software Engineering Team Lead on high-throughput messaging infrastructure. Earlier: national-scale public data platforms (company registry, procurement monitoring, government transparency).
Strongest at taking an ambiguous problem to a shipped system solo, hard systems work in Rust, and LLM evaluation/verification/orchestration. Most interested in agent infrastructure, dev tooling, LLM eval, and automation.
Open to: senior/staff IC or founding-engineer roles, or focused AI contract work.
Computer Vision engineer and former Product Owner at Mosaic (geospatial imaging). Background in applied mathematics; spent 5+ years on 3D reconstruction, SfM pipelines, multi-camera calibration, and LiDAR processing. And another 4 years before as an embedded engineer processing sensor data.
I've built calibration and processing pipelines for panoramic camera systems. Delivered large-scale photogrammetry projects for VFX clients including Netflix and Apple TV — hundreds of thousands of images per reconstruction. Owned products across calibration, image processing, and LiDAR pipelines end-to-end, provided support to the clients, and was responsible for communication with other HW and FW teams, including planning and roadmap discussions.
Now independent — focused on novel 3D reconstruction methods, calibration and Gaussian Splatting. Open to co-founding / product-engineer roles or consulting on hard Computer Vision problems. Short form of project based cooperation is also doable.
In my current job-free time I'm exploring Julia, Geometric Algebra for computer vision.
Staff Engineer / Lead Architect with 15+ years of experience specializing in high-stakes infrastructure, system overhauls, and early product velocity. I partner with tech leaders and founders as an embedded, hands-on technical consultant (15–30h/week) to bridge the gap between initial demos and enterprise-ready systems.
What I specialize in tackling:
- Applied AI & Automation: Integrating AI engines for practical backend workloads, including image classification pipelines, automated log processing, and embedding security scanners into CI/CD workflows to catch and patch vulnerabilities early.
- HealthTech & Diagnostics: Architected platforms integrating complex clinical diagnostic engines, lab systems, and data pipelines with ironclad compliance, deep telemetry, and strict authorization layers.
- Scale & Telemetry: Re-engineered legacy backends, database schemas, and standalone telemetry engines to smoothly process heavy, live data flows and scale to millions of users.
- High-Velocity E-Commerce: Built complex payment gateways, transactional networks, and checkout pipelines designed to handle high-stakes flows cleanly without failure.
- Technical Leadership & Mentoring: Led, unblocked, and upskilled engineering teams to level up implementation paths, accelerate prototyping velocity, and establish sound architectural blueprints.
Looking for direct engagements with founders, VPs of Engineering, or CTOs needing an autonomous technical leader to own core infrastructure paths without executive overhead. Direct client engagements only; no third-party placement agencies.
Project/Program Manager with 15+ years running cross-functional technical programs internationally, most recently on the Microsoft Xbox Certification program for HCLTech, owning delivery for a 50-100 person team spanning the US and Costa Rica.
A couple years back I spearheaded the build-out of a new test facility in Costa Rica from the ground up: budget, staffing, facilities/IT, vendor coordination, the whole thing through go-live. Day to day, I'm the one building and coordinating the project plans, schedules, and documentation that keep engineers and stakeholders on the same page. I'm used to operating across time zones, communicating with everyone from individual contributors up to executive leadership, and making sure teams have the information and resources that they need to run efficiently.
I have my Six Sigma Green Belt, and my PMP is currently in progress. I don't write production code, but I'm comfortable working alongside AI tools like Claude, ChatGPT, and Copilot, and I've been folding them into my PM and project workflows.
Looking for Project Manager, Program Manager, Project Coordinator, or similar roles.
Who I am: I'm an experienced (10+ years), versatile Full Stack engineer, specifically have passion in AI-driven application development. I'm seeking an opportunity to contribute to the success of a team while continuing to learn and expand my skills. I'm not working in a technical role at the moment, but am attempting to get back into the engineering world.

SEEKING FREELANCE/CONTRACT WORK — I build production software for founders and growing teams. Full-stack engineering across Rails, Vue, and React, with AI-augmented workflows. 25 years of shipping, leading teams, and owning technical direction.
I spent a decade as CTO at EMEX, growing the engineering team from scratch through private equity acquisition. Today I operate through Brightform Technology, working with founders who need senior-level engineering without a full-time hire. The kind of problems where product sense and architectural judgment matter as much as code output.
Past work:
* Led all frontend architecture for an IoT platform processing high-volume sensor data across nationwide deployments. Built real-time building floorplan visualization, time-series HVAC dashboards, and a modular device configuration system.
* First engineering hire → CTO at EMEX. Built the flagship real-time reverse auction platform that drove seven-figure annual sales. Grew and led a team of 6 through acquisition.
Best fit: founders with a clear idea and the budget to move fast. You might have Figma mockups, a vibe-coded prototype, or just a well-defined concept. I bring product direction alongside the engineering.
I'm looking for monthly/yearly "no-strings" sponsors, not employment. If any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent. Feel free to contact me (see HN bio).
I'm an international prizewinning academic likely to reduce my hours due to health concerns but very interested in fun, physics-heavy problems and out-of-bag collaborations.

Technologies: Medical Imaging, Magnetic Resonance and biomedical research in general -- and in a more nerdy context, HPC, MPI, C, C++, R, a bit of python (though, frankly, I do not like it) /tensorflow, and bash / mathematica / matlab. Not popular, I know. Oh, and LaTeX. I'll write a shopping list in LaTeX. You probably don't want that.
Research engineer with statistics and environmental-science training — I build sensor-to-score systems where the job is knowing whether the number means anything: frozen data contracts, QC gates, holdouts, and baselines before anyone trusts a model. Recently owned embedded thermal lab instrumentation end-to-end (Raspberry Pi/C++/Python/PyTorch); solo-shipped a macOS app (github.com/oxremy/BlinkMore). Open to research SWE, ML eval, analytics/data quality, instrumentation, or environmental data roles.

I'm at the AI Engineer World's Fair this week, so if you'd like to meet in person before I leave reach out!
I'm an AI/ML Systems Engineer specializing in high-performance deployments. Most recently I've built RL environments for frontier labs like OpenAI and Google DeepMind. Previously I've built distributed AI classifier systems handling 30K QPS, developed a neural network for Rocket League gameplay, and created platforms that cut model deployment time from 6 months to 6 hours. Saved $500K/yr in infrastructure costs through optimization at previous role. Former technical founder with experience in humanoid robotics and AI writing assistance. I write about my projects and musings on my Substack: https://thelisowe.substack.com/
Seeking roles focusing on ML infrastructure, model optimization, post-training, or full-stack AI/ML systems engineering.
I’m Mark, a Dutch product designer working from strategy to shipped code. Always have, it’s what got me hooked on design over a decade ago. Since, I’ve worn many hats working in startups and for myself.
I love collaborating with founders and small teams. By working across design, engineering, and product, I help them build simple, effective, and reliable software.
I’m ideally looking for a company where I get to go beyond making pictures of interfaces. A place where I get to work end-to-end from ideas to visuals to the finished product.
Senior data wrangler / “full-stack” data generalist with 10+ years of experience across analytics, data engineering, data platforms, data science, MLOps, applied AI, product, and business-facing data work.
I work best close to the action, going from vague operational problems to working tools. I’m comfortable talking to stakeholders, shaping the data/product solution, building the first version, and making it reliable enough for others to use. I like hands-on work: modeling data, writing code, building pipelines, training models when useful, creating dashboards and web apps, designing infrastructure, deploying tools, and iterating with users. I care about practical data work: making messy inputs understandable, building useful internal tools that improve business operations, avoiding overengineering, and choosing the simplest stack that gets the job done.
Past work includes:
- Leading analytics and optimization projects for operations-heavy businesses.
- Developing Python/SQL data pipelines, data models, data quality checks, Airflow workflows, and reliable reporting/analytics layers.
- Building dashboards, data apps, and client-facing reports with Superset, Tableau, Dash, Streamlit, Panel, and similar tools.
- Training and deploying ML models for forecasting, pricing, segmentation, churn, classification, entity extraction, and related use cases.
- Building AI/LLM prototypes for workflow automation and decision support.
- Running cloud data platforms with Kubernetes, Terraform, GCP, and AWS.
Looking for a small or scaling team that needs a senior hands-on data generalist: someone willing to work close to users, understand the business, build the data systems, and help turn rough ideas into useful tools.
I'm an engineer and data professional interested in team-building, consulting and architecting data pipelines. At Edmunds.com, I worked on a fairly successful ad-tech product and my team bootstrapped a data pipeline using Spark, Databricks, and microservices built with Java, Python, and Scala.
At ATTN:, I re-built an ETL Kubernetes stack, including data loaders and extractors that handle >10,000 API payload extractions daily. I created SOPs for managing data interoperability with Facebook Marketing, Facebook Graph, Instagram Graph, Google DFP, Salesforce, etc.
More recently, I was the CTO and co-founder of a crypto gaming startup. We raised over $6M and I was in charge of building out a team of over a dozen remote engineers and designers, with a breadth of experience ranging from Citibank, to Goldman Sachs, to Microsoft. I moved on, but retain significant equity and a board seat.
I am also a minority owner of a coffee shop in northern Spain. That I'm a top-tier developer goes without saying. I'm interested in flexing my consulting muscle and can help with best practices, architecture, and hiring.
Would love to connect even if it's just for networking!
Senior Backend & AI Engineer with 10+ years of industry experience, including 5+ years in crypto (Kraken / CryptoWatch, Glassnode). Work spans high-throughput Go microservices, large-scale data pipelines (Spark, Airflow, Iceberg, Kubernetes), and hands-on AI product development (LangGraph, RAG, pgvector). Most recently launched AI-driven, company-wide recommendations for crypto tokens & assets at Kraken. Mathematical background: Cambridge MMath, UCL MPhil in Probability (published paper). Looking for senior, autonomous roles at small companies or start-ups where I can drive technical decisions from architecture to production.
Full Stack Web Developer with over 15 years of shipping useful things. Broad-scoped human who also owns a music school, performs as a percussionist with improv groups, and gives bike and walking tours in the summer. I’m currently looking for part-time dev positions that will allow me to maintain my other interests.

Hi, I'm Iñaki. I specialize in compiler infrastructure and static analysis. My focus is on developing LLVM IR analysis passes for performance, security, and correctness diagnostics, as well as building auto-remediation tools. I also extend compiler frontends to support HPC codebases used in national research laboratories. Previously, I conducted research in HPC and bioinformatics, publishing in several D1 journals and achieving up to 200x speedups to enable genome-scale analysis of lncRNA interaction predictions. Outside of work, I enjoy running, weightlifting, and playing chess.
I am a designer with 6+ years of experience across product design, UI/UX, and digital product development. I have worked on real products across healthcare, music, fintech, logistics, and health tech, taking ideas from early-stage thinking through to shipped, usable experiences.
I enjoy working on complex problems, especially the kind that take time to understand properly and have meaningful, rewarding outcomes when solved well. I am comfortable working across startup environments and more established organisations, and I adapt quickly to different team structures and product stages.
As a designer, I work across the full process from discovery and problem framing through to interface design and delivery. I often take on multiple responsibilities within teams and focus on building clear, usable, and thoughtful product experiences.
I am currently looking for the right role where I can contribute strongly, work with good teams, and keep building products that actually solve real problems.

I specialize in building and deploying full stack reactive web platforms and integrations. I work at the architectural/design level and can build a modern web platform in a weekend.
I'm personally open to roles at established or founding teams.
15 years as a full-stack AI engineer, including onsite engineering and team leadership for US enterprises ADP and Time Warner Cable. I ship agentic AI products in 2 to 3 weeks, not months.
What I build:
-> Multi-agent systems with LangGraph, CrewAI, OpenAI Agents SDK, and AutoGen. Tool use, handoffs, planning loops, and guardrails that hold up past the demo.
-> Production RAG pipelines with pgvector, reranking, and evaluation. Not just a notebook.
-> AI-integrated full-stack apps on Next.js, Supabase, and Stripe. From MVP to scale.
Best fit: founders building agentic AI products who need senior engineering judgment, not just code. I have led and mentored engineering teams, so I can own architecture decisions and bring the rest of your team up to speed.
Open to fixed-bid projects, ongoing contract work, or fractional technical lead engagements. Competitive rates for the quality delivered.
Technologies: most experience is in C/C++ and OCaml, also comfortable with TypeScript/JavaScript/React Native/Expo, C#, Python, (System)Verilog, Rocq, and of course SQL. I usually pick up new stuff quickly, full laundry list on the resume.
Recent CS masters graduate, looking for opportunities starting in September. My background is in programming language theory (particularly logic/relational programming), so would be very happy to work with functional languages, compilers, automated reasoning, and/or formal verification. I also have a background in music (I'm a published composer!) so particularly interested in audio/music-related stuff as well. Curious to learn more about embedded/systems stuff. I've also done full-stack work across databases/cloud infrastructure/web APIs/frontends, and independently released a commercial music production plugin (Pivotuner, more info on my website).

I've really worked on just about everything. The last few years have been primary various node applications, the few years prior to that were mostly C#, prior to that mobile development...
Looking to get into something new. Open to pretty much anything at this point.
Senior iOS & Product Engineer with 18+ years of iOS development and 20+ years of software engineering experience. I’ve led development of award-winning apps featured by Apple, The New York Times, and Forbes, and have worked remotely with distributed teams for over a decade.
I’m looking for Senior/Lead native iOS roles where I can own product quality from architecture through implementation, with a strong focus on performance, user experience, and shipping polished apps.
Most AI agents in production are black boxes. When one fails, nobody can tell you why. I build the tooling that fixes that.
Tracea (tracea.dev): open-source observability for AI agents. Traces every LLM call by patching the HTTP transport layer, so there are no SDK wrappers, no framework lock-in, no code changes. Install and you see everything.
ObservAgent: local-first observability dashboard for Claude Code sessions. 1000+ active users, open source.
Before this: shipped a civic complaint platform to 50k+ users for a municipal government.
Looking for SWE engineer or AI engineer roles at startups building real production AI. High ownership, real users, hard problems.
Senior engineer with 10+ years of experience, while Scala is my strongest language, I'm a generalist and have shipped production code in Rust, Java, TypeScript, Ruby, and more. I'm keen on picking up new tools.
I believe in using the right tool for each task. Strong infrastructure background (AWS, cloud-native, distributed systems). US C-Corp for contracting.
I've attempted to bootstrap products myself so I understand what it takes
beyond writing code. I take full ownership end to end, I don't wait to be
told what needs solving.
Immediate availability because my whole team was laid off recently, I'm used
to work on US timezones. Open to senior IC or tech lead roles.
P.S: I also have decent experience leveraging AI to speed up my work, not vibe coding but holding AI-hands like I'd typically do with junior devs. I also have built multiple AI integrations.
Expert backend developer primarily focused on data engineering, mission critical/low latency/highly available systems, and AWS (certs: https://www.credly.com/users/jon-north.ad78f0c8). Happy to deal with greenfield or legacy or any mix of the two. I learn new things extremely quickly.
I prefer long term contract work, though I’ll help you with smaller things as well. W2 employment is a possibility if the fit is right. Whatever you’re doing with AI is also fine by me, and I’ll lead/adapt as appropriate.
Senior Unix/Linux infrastructure consultant with 20+ years of experience,
including SRE roles at Google, Two Sigma, and Reddit.
Available for short engagements (a few days to weeks, flexible scope) covering
server deployment and hardening (Linux, *BSD), DNS, networking,
configuration management (Puppet, Ansible), system health monitoring
(Prometheus, Grafana, Nagios), and backend service development in C,
Go, Perl, or Python — particularly for automation and infrastructure tooling.
Vendor-neutral. Code delivered is yours under a commercial-friendly open-source

I'm a Full-Stack Developer, Web Designer and Image Editor with over 25 years of professional experience. Problem-solver and avid learner, I'm used to working with small and large teams across enterprise, government and third sector. I take deadlines and delivery commitments very seriously.
Technologies: Ruby on Rails, PostgreSQL, MySQL, Sidekiq, Solid Queue, Redis, HotWire, Stimulus, ViewComponent, Tailwind, RSpec, AWS, Linux. Some Crystal from contract work at Kagi. Claude Code daily.
Senior Ruby on Rails developer, 11+ years across fintech, SaaS, e-commerce, and startups. Open to full-time remote or contract. What I'm best at: Performance work on existing codebases. Once optimized a set of Rails API endpoints from 90-120s down to 1-2s — measuring first, raw SQL where ActiveRecord produced bad queries, indexing, restructuring background jobs. External API integrations (5+ over my career: Google Maps, Chargebee, WhatsApp via 360dialog, SDB Groep, AFAS). Comfortable with the messy parts — retries, idempotency, webhook ordering, partial failures. Working with legacy and tests-nobody-touches. Reading before writing, refactoring without breaking things. As Tech Lead at clevergig (Dutch SaaS) for 3 years, I set up code review, bug tracking, and ownership processes for a long-lived codebase.
For fun: building a Rails app + ESP32 device that tracks power outages at my home — the device pings the API every minute, the Rails side aggregates into hours-with-power vs. without. Started during the post-2022 outages in Kyiv and kept evolving — a good way to keep Rails fresh and combine backend with a bit of hardware.
Hello! I'm Rachel, a Full-Stack Software Engineer with multiple years of experience in JavaScript, TypeScript, Ruby, and Python. I recently co-created Pendulum (https://www.pendulum-baas.dev/), a reactive Backend-as-a-Service for web applications. I also recently did freelance work incorporating AI agents into Intelliflo Office for a wealth management firm, and am looking for my next permanent role.
Software Systems Engineer 9 months into writing code. Built and shipped EZInvoice - a full-stack, local-first invoicing desktop app currently in private beta on the Microsoft Store(link available on request). Across my portfolio, I independently implement Clean Architecture featuring a fully isolated domain layer via imperative mapping with SQLAlchemy, explicit dependency inversion via zope.interface/zope.component, and native TypeScript interface ports on the frontend. I bring a special focus with 4,000+ hours of architectural blueprinting in Unreal Engine. My active projects include a custom C++ allocator, a Live Object Inspection Tool for devs via Win32/Webview2, as well as a Sentiment Analysis API using a custom tuned transformer(MPNet) with an 8-base mood Plutchik system via FastAPI.

Looking for full remote AI Engineer or Forward Deployed Engineer roles in companies of any size as I like new and unexpected challenges !
Senior DevOps / Site Reliability Engineer with 10+ years of experience building and operating large-scale cloud infrastructure and Kubernetes platforms. I've worked at two early-stage startups as well as with big tech companies including Microsoft and Google, delivering reliable, scalable infrastructure and developer platforms. Looking for Senior/Staff SRE, Platform Engineer, DevOps, Infrastructure Engineer, or Engineering Manager roles. Open to remote opportunities and international relocation.
About me: I’m a versatile Full Stack Engineer with 8+ years of experience building AI driven applications and scalable software systems. I’m passionate about creating impactful products, solving complex technical problems, and contributing to teams that value both innovation and execution. Known for refactoring ruthlessly, hunting root causes, and fighting for the users often while talking with my hands.
MS CS (AI/ML) — Northwestern '24 | Currently: AI/ML Engineer
Building real-time voice AI pipelines (sub-800ms latency) and RAG systems at Bhuvi IT. Previously shipped distributed 8-GPU training at Argonne National Lab (2TB astronomical data, 1 week → 20 hours) and graph-based entity resolution (0.96 F1) as standalone projects. Comfortable across the full stack from model training to serverless cloud deployment.
Open to AI/ML Engineering, Applied AI, Software Engineering or Data Scientist roles.
For one year I reverse-engineered the major education platforms — Google Docs, Microsoft Office, Nearpod, Kahoot, ect. — so that AI agents can drive them on a teacher's behalf and automate classroom workflows. The work runs in over 10,000 classrooms today.
Building agents against production code you don't control is harder than it sounds. The code is mangled, so first you have to understand how the app was built and then take it apart from the outside. It's reverse engineering, but it depends on knowing how to build the thing in the first place.
The role came with monthly compliance and security training centered on FERPA, so I'm fluent in handling student data responsibly. That's not new ground for me. I spent five years building on Drupal, which the most prestigious learning institutions still run today, and version control and access control were the hard part of every project. Student data is the same problem.
I've been building browser agents and browser automation since 2018, well before it was a category. That's paired with 13 years of building dynamic, data-heavy UIs for web and mobile.
I've also built admin dashboards for a custom legal document management system. And a CRM for email marketing, with a drag-and-drop interface for designing and branding email templates for social campaigns. I've taken several companies from 0 to 1, as a consultant and as a full-time employee, across fintech, streaming, real estate, education, marketing, and media. I've worked at a 130-person AI company and on a 7-person team where I wore every hat. I do my best work on small, fast-moving teams.
Hi Adam, sorry we missed you at the AI meetup at the Shop at the CAC yesterday, we had a bunch of demos and would have loved to see what you were working on too.
Eclectic mix of tech and business. I enjoy working on drive the project but also build tools, systems and dashboards. I also dabble with hackathons (https://devpost.com/edimaudo).
Hi, I'm Cristina, a Product Engineer / Full-stack Engineer with 5 years of experience, looking for a fully remote position. Based in Europe (CET), with flexibility to overlap with East Coast hours. B2B contract.

Recent work: re-architected two multi-terabyte OLTP tables (~2TB and ~1TB) handling 200+ writes/sec, improving scalability and reducing application-level complexity.
My work focuses on high-risk database migrations, dangerous schema remediation, hot-path optimization, and making existing systems scale without rewriting the product.
Open to consulting or full-time roles where data is central and performance matters.

I design things, then I make sure they actually ship. My toolkit is half intuition, half AI — Figma AI Suite, Antigravity & More. — and I know when to use which. I've put a music app in front of 550+ real users and a Figma plugin in 15+ countries, both from scratch. I work async, I work remote, and Product Analytics is where I come alive. Usability testing is where I'm still growing — and I'm okay saying that.
Senior technical Product Manager / CPO. CS from Imperial, MBA. Built an FX execution prototype from thesis to sub-second trading pipeline. Took a US consumer finance startup from blank page to full PRD, service blueprint, and compliance architecture. Spent a decade running a fintech startup network, mentoring founders from ideation to MVP. I'm at my best going from zero to one — architecture, sprint planning, and stakeholder alignment in the same week. If you need a strong tech product lead who gets deeply involved and moves fast, that's me.
Senior Product Designer | Design Engineer, 15+ years. I cover the whole design process and ship the front-end myself.
I've worked solo and in teams, at early startups and mature products, across EdTech, enterprise SaaS, fintech, healthcare, and dev tools. The work spans user research, UX and interaction, visual and brand craft, and design systems. I also write production HTML, CSS, JS, and React, so the design holds up in real code.
I can own a product end to end on my own, or slot into a team and move with it. I like early, messy problems and working close to founders and engineers.
Software engineer with over 8 years of experience focused on functional programming and declarative infrastructure. I like to solve hard/bizarre problems and my skills often shine when integrating niche tech.
I'm looking for Backend Engineering (especially functional programming) or DevOps/SRE opportunities.
Background in CS, statistics, and mathematics, with more than 15 years of experience in ML/AI x biology, particularly generative/deep generative models, representation learning, and causality. Strong understanding of experimental design, biological sequence analysis, genomics, and systems biology.
Experience includes a DPhil (PhD) from Oxford University, startups, and R&D positions. Interested in roles at startups, scaleups, and frontier labs working on foundation models for molecules and cells, disease biomarkers, and therapeutics.
CS graduate with 3+ years building and shipping production software at scale, I have worked on large scale production mobile apps to LLM-driven research systems, looking to bring systems, mobile and ML integration experience to high-impact engineering teams.
I build new projects and revitalize legacy code. I work mostly with Laravel and React/Inertia or Livewire.
I integrate modern tools pragmatically, adding real-time features via Websockets (Laravel Reverb etc) and AI capabilities like RAG for context-aware search and content generation.
I develop methodically – implementing tests for new features and maintaining clear documentation while keeping sharp focus on shipping tangible results. Through proactive communication, we'll collaboratively define the sweet spot between code quality and delivery pace.

What I bring
I enjoy working across the full lifecycle—from early MVPs to mature, high-scale products. I’m especially effective in environments where architecture clarity, pragmatic engineering decisions, and fast but sustainable delivery matter.
I focus on shipping software that works reliably in production and can evolve without technical debt bottlenecks.
I'm an engineer focused on deep learning systems and AI infrastructure.
Over the past few years I've been building NexusGrad, a deep learning framework written from scratch in modern C++ and CUDA to better understand how frameworks like PyTorch work internally.
The project includes:
• Custom tensor library (CPU/CUDA)
• Reverse-mode automatic differentiation
• Explicit computational graph runtime
• CUDA kernels for tensor operations and attention
• Flash Attention
• ALiBi attention
• Transformer components
• AVX2/OpenMP CPU kernels
• pybind11 Python bindings
• Numerical verification against PyTorch using finite-difference gradient checking
I'm interested in roles involving AI model optimization, LLM inference, deep learning runtimes, AI infrastructure, CUDA development, GPU software, distributed training/inference systems, and performance engineering.
Happy to work remotely worldwide or relocate with visa sponsorship.
Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. It was time to move on and so I relocated to Africa.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve yours.
I am open to work for a company anywhere as long as the work can be done fully remote from Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up a team for you.

Hi, I’m Mia. I’m a customer support / technical support generalist and frontend/full-stack developer with 2 years of customer-facing experience and 10+ years of self-taught technical work across web development, Linux/self-hosting, design, and automation.
I’m looking for frontend, full-stack, technical support, application/SaaS support, implementation, junior sysadmin, web operations, or internal IT roles. On the dev side, I’m especially interested in translating existing designs and product requirements into polished, accessible UI/UX. I can do original web design too, but my preference is implementation and product polish rather than being the sole visual designer.
At ABN AMRO I worked in Dutch and English customer care, supported customers with mobile banking and complex disputes, maintained KPI reporting, rebuilt a slow Power BI workflow into an Excel/Power Pivot version with documentation, and submitted 44 internal improvement proposals in two months.
Outside formal work I build web/software projects under mia.cx and run my own homelab with self-hosted k3s.
Technologies: Python, Ruby, C, C++, C#, JavaScript, TypeScript, PowerShell, Flask, SQL, PostGIS, Shapely, Unity, Unreal Engine, multiple assembly/machine languages, Windows user code and kernel drivers, Google Maps and other map APIs, geographic and airspace data
Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.
Solo full-stack builder. Most recently shipped InstaBid (getinstabid.app) — a multi-tenant SaaS lead capture platform for service contractors. React + Node + Postgres + Redis, Docker production deploy, custom analytics dashboard, branded portals, configurable per-tenant pricing engines. Built and deployed solo, end-to-end.
Best on greenfield MVP work or feature builds on React/Node/Postgres products. Flexible on scope — I ship fast and thoroughly regardless of project size.

I build the systems plumbing, concurrent pipelines, and secure runtime isolation that AI coding-agent startups are racing to ship.
AutoPatch-AI: An autonomous, self-healing code remediation agent built on a LangGraph state machine. I engineered a zero-trust Docker execution layer (network_disabled=True, 256 MB RAM / 128 PID hard limits), streamed real-time telemetry over lock-free thread queues via SSE, and moved from full-file diffs to Search/Replace block patching, cutting generation overhead by ~80%. Achieved a 100% resolution rate (5/5) on a custom Micro-SWE-bench harness with an average time-to-resolution of ~205 seconds.

My work includes computer-vision pipelines for fluorescence microscopy, confidence-aware time-series classification, diffusion/transformer-based scientific imaging research, and real-time wearable-sensor ML for Samsung Galaxy Watch.
I am especially interested in roles where I can build production-grade AI systems: applied ML, AI engineering, backend/data infrastructure for ML, computer vision, LLM/RAG systems, agentic AI tools, data science, and model evaluation platforms.
Interested in: Software Engineer, Machine Learning Engineer, AI Engineer, Applied Scientist, Data Scientist, Computer Vision Engineer, Generative AI Engineer, and ML Infrastructure roles. Open to startups and larger companies.
Native application development for iOS, Android, Mac and Windows with over a decade of experience. Creating and/or integrating APIs/SDKs. TV/Video applications on all platforms (Apple, Android, Amazon, Roku.) Extensive experience building products and platforms from the ground up.
Hi, I'm Madison Rickert, a senior software engineer who has been shipping code to production for over 20 years. Experienced engineering leader, presently all-in on agentic engineering, shipping code daily and finding new ways to push the envelope on its capabilities.
I'm an active contributor to several open-source MCP servers, build agent-first CLI tools, solve computer vision problems, and maintain a growing library of agent skills and agent harnesses I rely on daily.
For the past five-plus years I've been a partner and the in-house technical force at a creative studio. Before that, I was a senior IC and fractional engineering lead for a variety of startups and nonprofits, working across the full stack and mentoring teams of up to 5.
I have a penchant for both business and personal finance. Across my businesses and clients, I've been responsible for managing organizational finances and countless projects with typical budgets in the 5 to 6 figure range. Over the years this led me into financial automation, and I have several open-source projects in my portfolio in areas around agentic financial automation and investment management.
I'm also a working musician, and a hyper-organized Burning Man camp lead, best known around the Northern California festival scene for my saxophone performances for crowds up to 3,000 people.
I'm pivoting back to senior IC engineering after a long stretch as partner-operator. I'm excited to keep expanding the capabilities of AI, and my creative-tech and financial background will be a real asset to the right organization. If you're building software for creative work, media systems, music tech, financial tools, or AI tooling, I'd love to hear about it.
Proven solid problem solving, research, and mathematical skills (Computer Science Phd. with thesis on Topological Graph Theory). Over 4 years of experience in building AI-powered SaaS solutions and AppSec SAST tools.
Quite flexible over tech/languages and not limited by what is listed above.
I'm fine with freelance/contract work.
To make things go smoother, please consider including on your e-mail: any mention of Hacker News, if you pay based on location and the currency you're paying with, and details about the hiring process (how many interviews, etc.). If you need references for my most recent role, please ask.
Please, no recruiters or any hiring consultancy of any kind.
I am a backend-leaning full-stack engineer experienced in building production systems across Java/Spring Boot, Node.js/TypeScript, and Python.

Summary: I'm a product designer with 6+ years of product experience that can do some coding (even more with Claude/ Codex with my opinionated agentic engineering setup). Ideally looking for a jr. design engineer role so I can transition to design engineering/ software engineering. I've worked in the consumer app space for the last 4 years and have designed more onboardings and paywalls than anyone on Earth at the intersection of growth and design.
I've worked with many large apps on monetization, growth, and product challenges and have designed consumer apps that reached 600K/mo in revenue. I've also designed Bitcoin ATM UIs, dashboards, editor experiences, and marketing websites for brands and influencers.
Location: Los Angeles, CA

Willing to relocate: No (open to travel)
Fractional / advisory: Fractional CTO or CISO, or vCISO. Open to interim and part-time engagements.
Technology and security leader, first engineer to CTO and CISO over 8+ years at a healthcare ePRO startup. Built the platform from the first line of code to a secure, audited system serving ~100K users at 99.9% uptime. Led ISO 27001:2022 certification from scratch in 6 months with zero major nonconformities. Clean record: zero security incidents, 100% audit pass rate across HIPAA, GDPR, and FDA 21 CFR Part 11. Hired and led a 10-person eng team. Cut infra cost ~66% via an AWS to OCI migration.
Good fit if you need someone to stand up a security and compliance program, get audit-ready to unlock regulated or enterprise deals, or provide senior engineering leadership without a full-time hire.
Technologies: AWS, Oracle Cloud, ISO 27001, HIPAA, GDPR, FDA 21 CFR Part 11, backend APIs, iOS/Android, healthcare interoperability (HL7/FHIR/DICOM)
I have recently gotten a really killer job building a second space internet for the other billionaire, so it's kind of impossible to compete on salary.

PhD-trained engineer/manager (astronomy by training -- data is data). Currently Senior Data Science Manager at Hyundai Motor America's North American Safety Office, where I build large-scale vehicle telemetry pipelines, LLM-driven classification and RAG over enterprise data, and led department-wide LLM/AI adoption from technical workshops to production SDLC.
Previously managed a data science team at HeadSpin: built data science pipelines, killed error-prone spreadsheet workflows with proper APIs and dashboards, reimplemented the flagship data product to reduce costs, latency, and churn.
Looking for senior data / platform sorts of roles. Equally happy IC or manager -- I just want to ship. Open to full-time or fractional/contract; happy to even work on small projects you want to send my way to help get to know each other.
I build a lot on my own time, and the side projects are probably the best read on how I work:
- forohtoo -- Go service for awaiting Solana payments via SSE/NATS, with a clean `Await(memo, amount)` SDK. Writeup: https://brojonat.com/posts/forohtoo/
- IncentivizeThis (https://incentivizethis.com) -- bounty-based authentic ad platform using LLM-as-judge across Reddit, YouTube, Twitch, Instagram, HN, TripAdvisor. Writeup: https://brojonat.com/posts/incentivizethis/
- If I Go Missing (https://if-i-go-missing.com) -- dead-man's-switch service (Go + Temporal + Postgres + Twilio + Stripe).
- IYBI ("If You Build It [They Will Come]", https://iybi-twc.com) -- websites for independent workers, managed entirely by email. Customer pays via Stripe, emails an AI agent (Claude + Cloudflare Email Worker + R2 + K8s CronJob), the agent researches them, builds the site, and handles ongoing updates. My own consulting site runs on it.
Mostly Go or Python services running on my personal k8s cluster. Happy to talk shop or small projects we could work on together to assess fit.
Grad student in physics, ex-dev looking to transition into AI/ML or data science. Lately have been working on RAG and causal inference side projects, see my GitHub (https://github.com/BaronWolfenstein/causal_bench) for the latter.

GTM/Growth Operator & Fractional CMO. I build data-driven marketing systems and organic acquisition engines, transitioning startups from paid ad dependency to compounding organic channels. I like solving hard marketing problems.
What I've done for:
- CPA firm, I built a technical search and AEO pipeline that replaced a 25,000 USD per month paid ad spend, scaling organic traffic from zero to 210,000 monthly visits and increasing leads by 10x.
- For DTC-ecom brand, I restructured their checkout funnel, cart scripts, and localization layouts, boosting site-wide conversion rate by 250% and generating >1 million USD in annual revenue.
- For a frontier AI lab, I conducted 24 developer ICP interviews to validate commercial use cases and secured 2 enterprise design partners before we built a user interface.
- I designed an organic acquisition loop on Reddit that generated 300 active signups in 30 days with zero budget.
- For another DTC-ecom brand, I managed creator marketing campaigns and a performance marketing budget of 2.5 million USD per month across Southeast Asia.
I write technical content, build webhook-driven attribution pipelines, and set up analytics dashboards (PostHog, GTM) to make marketing performance transparent. I'm basically a one-man marketing team.

SEEKING FREELANCE WORK | UX/UI & web design
I help startups with the UX/UI and web design of their products. This includes web apps, websites, landing pages, copywriting, and I can assist with frontend development where needed. My background of launching my own products and being a full stack developer helps me create practical designs that balance usability, aesthetics, development effort, and performance. I work to fixed price quotes for self-contained projects.
---
The best live example of my work is Checkbot (https://checkbot.io/), a browser extension that tests websites for SEO/speed/security problems. The entire project is my own work including coding the extension itself, UX/UI design, website design (the homepage is optimised to load in 0.7 seconds, 0.3MB data transferred), marketing, website copy, and website articles on web best practices.

Hands-on CTO / principal engineer with 20+ years in software engineering. Technical co-founder, CTO/CPO, architect, fractional product owner, and engineering lead.
I work best at the intersection of architecture and implementation: designing data-heavy systems well, then staying close enough to the engineering to keep latency, operability, failure modes, and tradeoffs grounded in reality.
Selected work: fractional lead/architect for ground-up KPI platform rewrite; 5-person FTE team; company later exited for €10M. CTO/CPO for crypto/data product; live matching of 1M+ complex dynamic slices against continuous on-chain/off-chain metric streams; high-throughput, near-real-time latency suitable for trading workflows. ClickHouse-backed worker pipelines processing billions of rows/day while preserving near-real-time downstream availability.
Looking for freelance, contract, fractional CTO, principal engineer, technical lead, or data engineering work.
Best fit: backend-heavy products, analytics/data infrastructure, complex internal tools, low-latency pipelines, or early-stage teams that need one senior person with both breadth and depth.

Hi, I'm Branko. I am looking for a position in a small team where I can wear multiple hats: building features, handling support tickets, writing documentation, SEO.
I have an engineering degree in Geodesy/GIS and 5+ years of customer support experience. I've developed products like a text analysis tool, a fishing logbook app, and an app for easing certain customer support tasks (links on website).
If you need someone who is just as comfortable handling support and documentation as they are writing code, I'd love to chat.

Technologies: Full stack web dev for 15+ years in many forms, and many years of project and product management work, which is more what I'm looking for now. In recent years I've been focused on game development projects using Babylon/WebGL and working with C++ & Go server-side (MMO servers).
I have some cool projects! See my personal site for email and some of those projects:
https://brynnbateman.com/
My most popular project is https://www.idlequest.net/, which is an idle-game web-based version of classic EverQuest, complete with its original 3D graphics. It's basically the entire original EverQuest client recreated to run in a browser, but also has the option to play itself. Also made a new, custom MMO server in Go for it.
Looking mostly project/product management style work. I spent 10+ hours a day working on my own coding projects, which I'm proud of and think are really cool, but I think I'm a little too removed from the nitty gritty coding details these days to be a good IC candidate for a lot of places.
Open to contracting or full-time.

Most of what people call "data science" is now doable with an LLM and a weekend. I focus on the messy, ambiguous, regulation-heavy gnarly problems where nobody is sure what the right question is. Often it involves getting hands on to find the data and signal that's really needed.
What I've done:

Willing to relocate: No
Technologies: Rust, Python, Go · LLM/agent systems, multi-agent orchestration, LLM eval · browser automation + anti-detection (CDP) · data pipelines · dev tooling
Senior engineer & founder, 12+ years. Last ~2 years deep on Rust + LLM agents:
- Built a Rust CDP / browser-automation driver from scratch (anti-detection, agentic pipelines).
- Multi-agent orchestration + an LLM judge/eval layer - claim-level extraction and verification against ground truth — for my own AI SaaS.
- Built AI harness orchestrating different agents in their own native harnesses (agent-to-agent comms, clean room reviews, sandboxing)
- Wrote an architectural linter enforcing pure/effectful separation in large Rust codebases.
Before founding: Software Engineering Team Lead on high-throughput messaging infrastructure. Earlier: national-scale public data platforms (company registry, procurement monitoring, government transparency).
Strongest at taking an ambiguous problem to a shipped system solo, hard systems work in Rust, and LLM evaluation/verification/orchestration. Most interested in agent infrastructure, dev tooling, LLM eval, and automation.
Open to: senior/staff IC or founding-engineer roles, or focused AI contract work.

Heya, I am frontend developer with 4+ years of experience working with React, Next.js and much more. I have written some blogs about things I built.
I am always up for learning new things and applying it,if you are looking for someone who can be in your niche tech or something challenging,Then I am your guy.
Other than that, I love movies and books, mainly stories, world building, fantasy, and that would be awesome if I got a chance to work on anything in this
Interested in Job as well contract/freelance work.
Thanks :)
I can be flexible on time zones. No interest in relocating long-term, but I'd be happy to visit your team in person for a few days to break the ice.
My specialist skills:
- The Rust language, which has been my daily driver for more than a decade.
- Multimedia (video, audio, 2D rendering...)
- Performance optimisation (SIMD, GPGPU, parallel programming...)
Fields in which I'm highly experienced, but below specialist level:
- Web development, with a frontend bias (TypeScript, React, WebGL, WebAssembly...)
- Native development, especially low-level Win32.
- Communication and technical writing, both learned in a previous career.
I also have a modest level of experience in computer vision, greenfield R&D, game engine development, programming language development, and data compression. I can offer a 50% discount for any contract which seems highly educational; my current areas of interest include DSP, embedded programming, robotics, functional languages, Swift, and React Native.
Thanks for reading, and I look forward to hearing from you :-)

Senior data wrangler / “full-stack” data generalist with 10+ years of experience across analytics, data engineering, data platforms, data science, MLOps, applied AI, product, and business-facing data work.
I work best close to the action, going from vague operational problems to working tools. I’m comfortable talking to stakeholders, shaping the data/product solution, building the first version, and making it reliable enough for others to use. I like hands-on work: modeling data, writing code, building pipelines, training models when useful, creating dashboards and web apps, designing infrastructure, deploying tools, and iterating with users. I care about practical data work: making messy inputs understandable, building useful internal tools that improve business operations, avoiding overengineering, and choosing the simplest stack that gets the job done.
Past work includes:
- Leading analytics and optimization projects for operations-heavy businesses.
- Developing Python/SQL data pipelines, data models, data quality checks, Airflow workflows, and reliable reporting/analytics layers.
- Building dashboards, data apps, and client-facing reports with Superset, Tableau, Dash, Streamlit, Panel, and similar tools.
- Training and deploying ML models for forecasting, pricing, segmentation, churn, classification, entity extraction, and related use cases.
- Building AI/LLM prototypes for workflow automation and decision support.
- Running cloud data platforms with Kubernetes, Terraform, GCP, and AWS.
Looking for a small or scaling team that needs a senior hands-on data generalist: someone willing to work close to users, understand the business, build the data systems, and help turn rough ideas into useful tools.
Remote: Yes
Relocation: Case-by-case
I'm an engineer and data professional interested in team-building, consulting and architecting data pipelines. At Edmunds.com, I worked on a fairly successful ad-tech product and my team bootstrapped a data pipeline using Spark, Databricks, and microservices built with Java, Python, and Scala.
At ATTN:, I re-built an ETL Kubernetes stack, including data loaders and extractors that handle >10,000 API payload extractions daily. I created SOPs for managing data interoperability with Facebook Marketing, Facebook Graph, Instagram Graph, Google DFP, Salesforce, etc.
More recently, I was the CTO and co-founder of a crypto gaming startup. We raised over $6M and I was in charge of building out a team of over a dozen remote engineers and designers, with a breadth of experience ranging from Citibank, to Goldman Sachs, to Microsoft. I moved on, but retain significant equity and a board seat.
I am also a minority owner of a coffee shop in northern Spain. That I'm a top-tier developer goes without saying. I'm interested in flexing my consulting muscle and can help with best practices, architecture, and hiring.
Would love to connect even if it's just for networking!

Most AI agents in production are black boxes. When one fails, nobody can tell you why. I build the tooling that fixes that.
Tracea (tracea.dev): open-source observability for AI agents. Traces every LLM call by patching the HTTP transport layer, so there are no SDK wrappers, no framework lock-in, no code changes. Install and you see everything.
ObservAgent: local-first observability dashboard for Claude Code sessions. 1000+ active users, open source.
Before this: shipped a civic complaint platform to 50k+ users for a municipal government.
Looking for SWE engineer or AI engineer roles at startups building real production AI. High ownership, real users, hard problems.
I believe in using the right tool for each task. Strong infrastructure background (AWS, cloud-native, distributed systems). US C-Corp for contracting.
I've attempted to bootstrap products myself so I understand what it takes beyond writing code. I take full ownership end to end, I don't wait to be told what needs solving.
Immediate availability because my whole team was laid off recently, I'm used to work on US timezones. Open to senior IC or tech lead roles.

Expert backend developer primarily focused on data engineering, mission critical/low latency/highly available systems, and AWS (certs: https://www.credly.com/users/jon-north.ad78f0c8). Happy to deal with greenfield or legacy or any mix of the two. I learn new things extremely quickly.
I prefer long term contract work, though I’ll help you with smaller things as well. W2 employment is a possibility if the fit is right. Whatever you’re doing with AI is also fine by me, and I’ll lead/adapt as appropriate.

Senior Ruby on Rails developer, 11+ years across fintech, SaaS, e-commerce, and startups. Open to full-time remote or contract. What I'm best at: Performance work on existing codebases. Once optimized a set of Rails API endpoints from 90-120s down to 1-2s — measuring first, raw SQL where ActiveRecord produced bad queries, indexing, restructuring background jobs. External API integrations (5+ over my career: Google Maps, Chargebee, WhatsApp via 360dialog, SDB Groep, AFAS). Comfortable with the messy parts — retries, idempotency, webhook ordering, partial failures. Working with legacy and tests-nobody-touches. Reading before writing, refactoring without breaking things. As Tech Lead at clevergig (Dutch SaaS) for 3 years, I set up code review, bug tracking, and ownership processes for a long-lived codebase.
Recent stops: FastCTO (fintech), Rail Europe, Fitjourney.ai, Kagi (Crystal backend), clevergig (Tech Lead).
For fun: building a Rails app + ESP32 device that tracks power outages at my home — the device pings the API every minute, the Rails side aggregates into hours-with-power vs. without. Started during the post-2022 outages in Kyiv and kept evolving — a good way to keep Rails fresh and combine backend with a bit of hardware.

For one year I reverse-engineered the major education platforms — Google Docs, Microsoft Office, Nearpod, Kahoot, ect. — so that AI agents can drive them on a teacher's behalf and automate classroom workflows. The work runs in over 10,000 classrooms today.
Building agents against production code you don't control is harder than it sounds. The code is mangled, so first you have to understand how the app was built and then take it apart from the outside. It's reverse engineering, but it depends on knowing how to build the thing in the first place.
The role came with monthly compliance and security training centered on FERPA, so I'm fluent in handling student data responsibly. That's not new ground for me. I spent five years building on Drupal, which the most prestigious learning institutions still run today, and version control and access control were the hard part of every project. Student data is the same problem.
I've been building browser agents and browser automation since 2018, well before it was a category. That's paired with 13 years of building dynamic, data-heavy UIs for web and mobile.
I've also built admin dashboards for a custom legal document management system. And a CRM for email marketing, with a drag-and-drop interface for designing and branding email templates for social campaigns. I've taken several companies from 0 to 1, as a consultant and as a full-time employee, across fintech, streaming, real estate, education, marketing, and media. I've worked at a 130-person AI company and on a 7-person team where I wore every hat. I do my best work on small, fast-moving teams.

Like this Ask HN: Recommend employers with positive social impact [https://news.ycombinator.com/item?id=31518945], I am looking for similar work, but I am open to work on any interesting project. I am a European software developer who has lived and worked on four continents. It was time to move on and so I relocated to Africa.
I have more than a decade of experience running a company, doing software development, support and training and mentoring adults and students, as well as working on educational projects, and I am willing to take on a mixture of roles as needed to support a project.
I value good teamwork over fancy tech, and I don't shy away from working on legacy code. I am primarily motivated by solving problems, so let me help you solve yours.
I am open to work for a company anywhere as long as the work can be done fully remote from Africa.
While I could find a job elsewhere I believe that the experience living in an area where my work is going to have an impact gives me a better understanding of the needs of the location I am serving. Whether it is through direct contact with clients and users or just by being part of a local community and learning about the reality of living there.
In addition, I want to use some of my income to hire local interns and junior developers and train them in order to pass on my experience. I also sponsor children that otherwise can't afford to go to school (see my website). If you want to support this, I would love to work with you. Also if you are interested in hiring African developers yourself. I can help you build up a team for you.
I’m looking for frontend, full-stack, technical support, application/SaaS support, implementation, junior sysadmin, web operations, or internal IT roles. On the dev side, I’m especially interested in translating existing designs and product requirements into polished, accessible UI/UX. I can do original web design too, but my preference is implementation and product polish rather than being the sole visual designer.
At ABN AMRO I worked in Dutch and English customer care, supported customers with mobile banking and complex disputes, maintained KPI reporting, rebuilt a slow Power BI workflow into an Excel/Power Pivot version with documentation, and submitted 44 internal improvement proposals in two months.
Outside formal work I build web/software projects under mia.cx and run my own homelab with self-hosted k3s.

Hi, I'm Michael Geary. I've programmed in many languages and environments over the years. Some of my current interests are:
• Developer experience. I love helping my fellow developers solve problems, and building tools to make their jobs easier and more enjoyable.
• Aviation and geographic data. For example, airspace and obstacle data importers for Wing; election results and voter information maps for Google; many interactive maps for other companies.
• Hardware interfacing. In a way, I am a "full stack" developer, but my stack may involve a front end to a piece of hardware rather than the cloud. I first got into programming via ham radio, so RF hardware remains an interest.
• Designing and building APIs. Too often an API is designed by exposing the internals of whatever system provides the API. My philosophy is the opposite: start with the apps. I like to build a series of sample apps before starting on the API. This way I can imagine what API will make those apps and others like them easy to build.
• Talk with users! I don't like to sit in a back room cranking out code. I want to make sure it's the right code for what my users need, and that it's easy to maintain and improve as we learn more about what they want.
Open to full time or contract.

I'm a senior and highly experienced IT developer, architect, DevOps and agentic engineer.
I build (and fix) systems across the full stack — engineering, architecture, infrastructure, security, operations. After three decades of battle-tested experience there isn't a failure mode I haven't already seen.
As an agentic engineer I know how to use AI tools intelligently and prevent failures with well-written specs and guardrails. I know where they fail and why they often makes the same mistakes junior developers make. I see this anytime I get called in to fix what AI-first teams built too fast.
A few things I've done:

Hi, I'm Madison Rickert, a senior software engineer who has been shipping code to production for over 20 years. Experienced engineering leader, presently all-in on agentic engineering, shipping code daily and finding new ways to push the envelope on its capabilities.
I'm an active contributor to several open-source MCP servers, build agent-first CLI tools, solve computer vision problems, and maintain a growing library of agent skills and agent harnesses I rely on daily. For the past five-plus years I've been a partner and the in-house technical force at a creative studio. Before that, I was a senior IC and fractional engineering lead for a variety of startups and nonprofits, working across the full stack and mentoring teams of up to 5. I have a penchant for both business and personal finance. Across my businesses and clients, I've been responsible for managing organizational finances and countless projects with typical budgets in the 5 to 6 figure range. Over the years this led me into financial automation, and I have several open-source projects in my portfolio in areas around agentic financial automation and investment management. I'm also a working musician, and a hyper-organized Burning Man camp lead, best known around the Northern California festival scene for my saxophone performances for crowds up to 3,000 people.
I'm pivoting back to senior IC engineering after a long stretch as partner-operator. I'm excited to keep expanding the capabilities of AI, and my creative-tech and financial background will be a real asset to the right organization. If you're building software for creative work, media systems, music tech, financial tools, or AI tooling, I'd love to hear about it.

I am a backend-leaning full-stack engineer experienced in building production systems across Java/Spring Boot, Node.js/TypeScript, and Python. I thrive on solving complex backend problems, managing enterprise-grade infrastructure, and automating data-intensive processes.
Engineering Experience & Achievements:
Enterprise Backend & Pricing Logic: Navigated and troubleshot complex, enterprise-grade pricing engines. Traced intricate business logic through the data layer, stored procedures, and configuration scoring systems to accurately resolve high-stakes financial discrepancies. Systemic Problem Solving: Spearheaded large-scale SQL investigations, identifying systemic batch-job failures that affected over 110,000 accounts and billions in stranded funds. Strengthened platform stability by tracing logic mismatches across frontend and backend environments, engineering bulk database corrections, and writing integration tests to validate complex caching behaviors.
Full-Stack Development & Conversion: Led backend development for a content-prediction platform, taking the product from concept to a live environment. Rebuilt high-traffic company websites, driving a 15% increase in user conversion rates through re-engineered React interfaces and optimized backend infrastructure.
Data Engineering & Pipelines: Architected data processing flows and model pipelines in Python, establishing the foundational frameworks for optimization intelligence layers. Engineered automated data ingestion and sanitization pipelines for high-dimensional datasets to support proprietary AI analysis.
Key Projects:
Production Data-Harvesting: Engineered a modular Python/Playwright engine for B2B lead generation, leveraging stealth browsing, proxy integrations, and Pydantic schemas to maintain 99%+ uptime and high data integrity.
Secure Systems: Architected a zero-trust multi-tenant application with database-level isolation, Spring Security 6/JWT authentication, and ACID-compliant PostgreSQL schemas.
Personal Automation: Built and maintained a self-built infrastructure of terminal-based Python CLI tools for daily productivity, automated via MacOS LaunchAgents.
Summary: I'm a product designer with 6+ years of product experience that can do some coding (even more with Claude/ Codex with my opinionated agentic engineering setup). Ideally looking for a jr. design engineer role so I can transition to design engineering/ software engineering. I've worked in the consumer app space for the last 4 years and have designed more onboardings and paywalls than anyone on Earth at the intersection of growth and design.
I've worked with many large apps on monetization, growth, and product challenges and have designed consumer apps that reached 600K/mo in revenue. I've also designed Bitcoin ATM UIs, dashboards, editor experiences, and marketing websites for brands and influencers.
Technology and security leader, first engineer to CTO and CISO over 8+ years at a healthcare ePRO startup. Built the platform from the first line of code to a secure, audited system serving ~100K users at 99.9% uptime. Led ISO 27001:2022 certification from scratch in 6 months with zero major nonconformities. Clean record: zero security incidents, 100% audit pass rate across HIPAA, GDPR, and FDA 21 CFR Part 11. Hired and led a 10-person eng team. Cut infra cost ~66% via an AWS to OCI migration.
Good fit if you need someone to stand up a security and compliance program, get audit-ready to unlock regulated or enterprise deals, or provide senior engineering leadership without a full-time hire.

PhD-trained engineer/manager (astronomy by training -- data is data). Currently Senior Data Science Manager at Hyundai Motor America's North American Safety Office, where I build large-scale vehicle telemetry pipelines, LLM-driven classification and RAG over enterprise data, and led department-wide LLM/AI adoption from technical workshops to production SDLC.
Previously managed a data science team at HeadSpin: built data science pipelines, killed error-prone spreadsheet workflows with proper APIs and dashboards, reimplemented the flagship data product to reduce costs, latency, and churn.
Looking for senior data / platform sorts of roles. Equally happy IC or manager -- I just want to ship. Open to full-time or fractional/contract; happy to even work on small projects you want to send my way to help get to know each other.
I build a lot on my own time, and the side projects are probably the best read on how I work:
- forohtoo -- Go service for awaiting Solana payments via SSE/NATS, with a clean `Await(memo, amount)` SDK. Writeup: https://brojonat.com/posts/forohtoo/ - IncentivizeThis (https://incentivizethis.com) -- bounty-based authentic ad platform using LLM-as-judge across Reddit, YouTube, Twitch, Instagram, HN, TripAdvisor. Writeup: https://brojonat.com/posts/incentivizethis/ - If I Go Missing (https://if-i-go-missing.com) -- dead-man's-switch service (Go + Temporal + Postgres + Twilio + Stripe). - IYBI ("If You Build It [They Will Come]", https://iybi-twc.com) -- websites for independent workers, managed entirely by email. Customer pays via Stripe, emails an AI agent (Claude + Cloudflare Email Worker + R2 + K8s CronJob), the agent researches them, builds the site, and handles ongoing updates. My own consulting site runs on it.
Mostly Go or Python services running on my personal k8s cluster. Happy to talk shop or small projects we could work on together to assess fit.
