What I'm looking for

I'm looking for challenges with technical and strategic impact, where I can adapt AI-assisted development to the project while retaining control of architecture and quality.

I developed Predicta FC, a cross-platform sports prediction app for the 2026 World Cup, for a client. It includes private leagues, global rankings, and a serverless backend that scores predictions and synchronizes rankings.

At FYNKUS, I refactored a legacy building-community app using Clean Architecture and Riverpod, and integrated ChatGPT for real-time translation in 11 languages. My work has also included Decathlon Spain’s Decalinks employee app and web platform, plus mobile and web products for clients across sport, education, and public services.
