About Me

I'm a Data Scientist with over seven years of experience transforming complex datasets into strategic product decisions. Currently at Meta, I serve as a primary analytics domain expert for the consumer hardware portfolio — including Ray-Ban Meta glasses, VR/Quest, and Portal — within Reality Labs.

My work spans the full analytics lifecycle: from designing metric frameworks and building logging pipelines to running experimentation programs and delivering leadership-level insights that shape product roadmaps. I thrive in ambiguous, early-stage product environments where defining what to measure is as important as the measurement itself.

Before Meta, I built ML credit scorecards at Carbon (fintech), drove product analytics at Cabify (mobility), and researched Smart Cities technologies at Ferrovial. I hold a degree in Chemical Engineering from Universidad Politécnica de Madrid and transitioned into data science through General Assembly's immersive program in London.
