that scale.
12+ years of experience crafting high-availability software, leading teams, and shipping products across fintech, e-commerce, and travel tech.
A bit about me
I'm a Software Project Leader at Mercado Libre, where my team builds fraud scoring systems that evaluate over 1 billion transactions per day across Latin America. Before Mercado Libre, I led 15+ engineers at Sabre building high-throughput microservices with 99.7% uptime, and worked on payment systems at Verifone. My journey started in Cuba, where I earned a CS degree from UCI with a thesis on AI-driven decision-making and published research on open-source desktop environments. Since moving to Uruguay in 2021, I've built products across fintech, travel tech, and marketplace fraud prevention at continental scale.
