I build systems that scale and interfaces that feel alive.

My stack spans Node.js, NestJS, React, and cloud infrastructure — but my obsession is the boundary where software meets intelligence. AI agents, vector databases, generative workflows: this is where engineering becomes something closer to craft.

I've managed distributed teams of 30+, shipped AI-powered healthcare platforms, and built payment systems handling millions. Based in Barcelona. Open to ambitious problems that push both engineering and design forward.
