About

I work across backend, systems and software quality. I start from the problem, not the technology: requirements and constraints decide the stack.

Robustness, to me, is not complexity: it is code that is easy to change. Every bug becomes a test that keeps it from coming back.

I work mainly with Rust, TypeScript and Python, in reproducible environments (Nix, Docker), with testing discipline: TDD, mutation testing and CI. I use AI agents with engineering discipline and judgement.
