About

Who I Am

I'm a passionate Full Stack Developer and AI enthusiast from Barcelona, currently wrapping up my BS in Software Engineering at FIB UPC (graduating June 2026). The only thing remaining is my bachelor's thesis, which I'm developing around Knowledge Graphs and AI Agents.

Working full-stack at K·Factor, building mobile apps and AI agents. On the side, I'm developing Livea—an AI-powered ticketing system for real estate managers, and providing AI consulting for small and medium businesses.

I'm drawn to startups focused on real-world problems, shipping simple things that work rather than overengineering. I'm eager to transition more deeply into AI, learning as much as possible while contributing wherever I can.

When I'm not coding, you'll find me at the gym , or fishing by the sea.
