About

I'm an engineer-turned-product builder based in Brighton, with an MSc in Electronic & Electrical Engineering from Comillas Pontifical University and exchange years at the University of Illinois and Chalmers University.

Over the past five years I've worked across technology operations, analytics, and product development — at IBM (cloud incident response for financial institutions), Willis Towers Watson (HR analytics dashboards for international clients), and British Airways (frontline operations for 200+ passengers per flight).

Today I focus on building products end-to-end. The pieces above are all live, all mine, and all shipped solo. I write in Spanish, English, and French — and I'm looking for product, engineering, or analytics roles where I can keep building.
