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.

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.

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 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 :-)
