About
I’m a full-stack engineer based in San José, Costa Rica. I specialize in TypeScript, React, React Native and Node, and I like the hard parts — architecture, complex business rules, and the edge cases nobody else wants.
Always learning — new frameworks, new languages, new problems. Technical depth is the foundation everything else is built on. Let’s build something together.
