I'm someone who enjoys building fast, reliable systems and solving complex technical problems. Over the past year, I've worked on everything from ultra-low-latency trading engines in C++ and Rust to building a high-performance CPU emulator from the ground up. I’ve had the chance to work with lead backend developers at startups, optimize systems for scale. I’m comfortable working across the stack, whether that’s building APIs with Express.js and TypeScript or diving deep into Kafka pipelines and distributed architectures. I care about writing clean, maintainable code, and I’m always up for learning something new or tackling tough challenges with a team.

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.

Location: Portland, OR, USA (PT)

Remote: Yes

Willing to relocate: No

Technologies: Figma, design systems, information architecture, accessibility (WCAG), user research and synthesis; popular front-end frameworks such as React and Angular, plus Node.js, Tailwind CSS, HTML/CSS/JavaScript, Vercel, and Claude Code for AI-assisted frontend prototyping

Outcome-driven product designer with 10+ years across regulated industries and complex, data-dense systems. My work spans fintech and multiple Fortune 500 platforms in media, beverage, and semiconductor, from consumer-facing flows to internal operational tooling.

Location: Europe

Remote: Yes. 12+ yrs, comfortable fully async across US/EU hours

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.

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've been working on production-grade AWS deployments for over 10 years, so it's a bit hard to frame my experience/skill set. That being said, if you need help with almost anything AWS - architecture, infrastructure, performance, scale - feel free to reach out. Although versed in Well-Architected/multi-region/multi-account, I strive to supply the simplest solution for your particular scenario.

Resume: https://bit.ly/3B3o65M (It links to my CV repo at Github, pinky promise. You can also visit github.com/<hnusername>.)

I'm not actively looking (hence why my resume link is obfuscated like that) but I'm at least interested in getting a feel for the market right now. That said, I'm willing to consider a position with a great fit for my skill set and career goals.

Here's my pitch: I have experience in a multitude of industries and positions. From improving legacy infra and processes in an established telco company to scaling a fast-moving startup from 200K to 2M users. In my free time, I love writing Code That Is Poetry but day-to-day I am not an idealist engineer who doesn't compromise. Well-engineered code is clean and correct but correct above all else.

Oh, also, I'm great at writing documentation. I consider myself introverted but apparently my communication skills are above average for Software Engineers. I also pride myself on my humility and modesty. :v

I'm currently a backend engineer developing features and improving infra for an online game with millions of daily active users. I'd love to explore other technical positions in the games industry short of joining a AAA studio because (a) I don't want to crunch and (b) my skill set does not lay that way; other tech-creative industries would also appeal to me! Another particular interest is in B2C businesses where the 'C' is software developers. I'd love to chat and network about opportunities; if you think you have a product that could benefit from my skill set, drop me a line!

Experienced software developer, mostly looking for freelance work, but also happy to discuss full-time employment.

    Location: UK
    Remote: Yes
    Willing to relocate: No

Particularly good at cleaning up messes! Suitable contracts might include legacy module rewrites, performance improvements, or the daunting new feature which nobody on your team wants to tackle.

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 :-)
