Full Stack Engineer

I build offline-first apps

About

I'm a full stack engineer based in Benin. I care less about which framework is on the page than about how a system is shaped — what it has to survive, where it breaks, and what has to stay true for it to keep working.

Most of what I know came from building the thing, then rebuilding it once I understood it. I’m curious about AI agents and robotics, and lately I stopped only reading about them and started shipping toward them.
