About

The unusual path

I spent 18 years as a classically trained chef before moving into tech full-time. But I've been building for the web for 32 years — since before CSS existed. That dual background gave me something most developers don't have: an obsessive eye for process, an understanding of systems under pressure, and the ability to think about how things actually get used — not just how they get built.

I ran a web agency. I've shipped products, managed infrastructure, and designed architectures from database schema to deployment pipeline.

Now I work at the intersection of product thinking, systems architecture, and AI-augmented engineering. I use tools like Claude Code not as a novelty but as a core part of my development workflow — building multi-agent systems, automating security reviews, and shipping faster than teams three times my size.

I think in systems. I build things that work. And I care deeply about the craft.
