About me

Full stack developer from Brazil, based in Bucaramanga (Colombia). Self-taught from a young age — got into code early to help my family — and grew into shipping real production systems through trial, error, and a lot of broken builds. Four years now writing code that actually has to stay up.

Backend is where I'm strongest: Java, Spring Boot, microservices. But I work the full stack — Angular and TypeScript on the frontend, Node.js and Express when the project asks for it, and AWS as my default cloud. I obsess over clean architecture, response times, and APIs that don't make the next dev cry.

Backend                Frontend              Cloud
Java · Spring Boot     Angular · TypeScript   AWS · Docker · K8s

Status: Open to work · Backend / Full-stack roles · Remote LATAM, EU, US
