Collomb.

Product-minded full-stack, rooted in backend and architecture. I build products end-to-end, from idea to deploy; I apply AI when it solves a real user problem, not when it looks good in the pitch.

About

I've been building products for 7 years. I started in backend and architecture and gradually moved toward product: today I'm comfortable from cross-service integration decisions down to the UX detail that makes something feel right.

I work remotely for US fintech from Argentina. I like problems where engineering and product meet.
