About me — 01

I build software that's fast, honest, and obvious to use. Good engineering and good design aren't separate jobs to me — they're the same one.

I'm a Full Stack Developer based in Madrid. I work across the whole stack — from database schemas and APIs to the pixels people actually touch — and I'm comfortable owning a feature from the first migration to the final hover state.

When I'm not building my own products, I help small businesses turn rough ideas into tools they genuinely rely on.
