San José, Costa Rica (GMT-6)

Senior Fullstack Developer with 15+ years building software across front-end, back-end, and mobile.

From Colombia, currently living in San José, Costa Rica. I’ve led technical teams, migrated legacy systems, and shipped products used by thousands of users.

I’m aiming to keep growing toward a team-lead role in a large company, where I can contribute at scale, strengthen engineering culture, and guide high-impact technical decisions.
