About

I spent 10 years as a senior iOS developer, shipping apps used by thousands. I learned to value clean architecture, maintainable code, and thoughtful developer experience.

I've since pivoted to backend and AI engineering — drawn to the scalability challenges and creative potential of building intelligent systems. Today I work at the intersection of Go services, container orchestration, and AI tooling.

Outside of work, I helped co-found SwiftAveiro, Portugal's largest iOS-dedicated conference. I still believe the best developer communities are workshop-shaped.

Community

SwiftAveiro

I co-founded SwiftAveiro, Portugal's largest iOS-dedicated conference. We pioneered a workshop-based format — originally seen at SwiftAlps — that the developer community widely embraced.

Across three editions we brought together hundreds of iOS developers for hands-on, mentor-led sessions in Aveiro.
