I engineer backends that scale.
4+ years building production systems with Node.js, Angular, and cloud infrastructure. Backend-heavy, full-stack capable. Based in Costa Rica — open to remote.
About Me
Full-stack engineer with a backend soul.
I build efficient, scalable, and maintainable systems. Comfortable across the full stack but strongest on the backend — REST APIs, real-time infrastructure, cloud deployments, and the invisible work that keeps production healthy.
If you can describe it, I can engineer it.
