About me

Building games people love to play

I'm a Senior Unity Developer based in Galicia, Spain, specialising in multiplayer systems and live-service infrastructure for digital collectible card games.

Over 15 years I've taken products from prototype to production, owned client–server architecture end-to-end, and kept long-running live games stable through continuous balancing, event delivery, and performance work.

I care about maintainable code, clean architecture, and sharing knowledge — I've mentored junior developers and contributed to Agile process improvements throughout my career.
