The helmsman — the one who reads the wind, holds the course, and keeps the ship on track.
Approach
I embed in your team, understand your domain, and ship production-ready code. No hand-off friction — I take features from architecture to deployment, with clean code and clear communication at every step.
I help you make solid technical choices. Data modelling, API contracts, system design — I bring the expertise so your team can move fast with confidence.
From requirements to production, I deliver complete features. You stay in control of the roadmap — I make sure what ships is clean, tested, and shipped on time.
I adapt to your tools, your processes, and your people. I keep communication clear and feedback loops short — whatever mix of sync and async fits your team. No silos, no surprises.
Security is not an afterthought. OAuth with server-only cookies, strict CSP with nonces, XSS prevention, least-privilege permission models — I bake these in from day one. I maintain ongoing CVE watch on sensitive dependencies and treat security hygiene as a first-class engineering concern.
Stack & Practices
Hexagonal architecture, dependency injection, clear boundaries between domain and infrastructure. Code that’s easy to test, extend, and hand off.
BDD and TDD aren’t buzzwords — they’re how I make sure what I ship actually works. Tests document intent, catch regressions, and give your team confidence to change things. Thorough reviews and short feedback loops.
I take the time to understand your domain deeply before writing a line of code. Good engineering starts with the right questions, not the fastest keyboard.
I use Claude Code and AI coding tools daily — not as a crutch, but as a multiplier. I know how to prompt, review, and steer AI output to ship faster without sacrificing quality.

Four projects, four identities — each taken from the first commit to production, with its own design language. Different problems, one standard of craft.
— the private vocabulary of a trade
Lint the rules you never wrote down.
A voice linter powered by machine learning. argot learns your repo’s voice from its git history, then flags the hunks that don’t sound like your team. Runs locally — no LLM, no cloud, no GPU.
— effraction — a break-in, entry by force
React components, written as Effect programs.
Write React components as Effect programs. The same component body runs in a SPA, on a server, in a Web Worker, or as an RSC.
— the lookout in the crow’s nest
Eyes on the horizon.
Local-first supervision for AI coding agents — real-time visibility, loop & drift detection, cost guardrails, and rollback. Your AI writes the code; you keep the helm.
— to catch the world breaking its own rules
Can you beat an AI that learned physics from scratch?
A browser game pitting your physics intuition against an AI world model. Spot the clip that breaks physics — while a JEPA-style world model (LeWM) catches every glitch and scores a perfect 10/10.
About
I'm Damien — a curious tinkerer since the days I was dismantling every piece of electronics at home (sorry, Mom). 31 years old, married to the wonderful Clara who tolerates my late-night coding sessions, and proud dad to Basile who already beats me at board games.
What drives me is the craft. Part of the SoCraTes Belgium community, I believe great software is about clean design, tight feedback loops, and the discipline to keep learning. TDD, continuous refactoring, and AI-augmented workflows — that's how I sleep at night knowing my code won't wake anyone up at 3 AM.
The rise of AI in development? Fascinating — but when agents write code unsupervised, things drift fast. Context window limits, hallucinated logic, quality erosion. That's why I built Vigie: the more powerful our tools, the more we need control. When I'm not coding, you'll find me losing at Terraforming Mars or chasing whatever shiny tech caught my eye.
