01. About

Who I am

Novo Hamburgo, Brazil, open to relocation to Portugal 🇵🇹

I've been figuring out how technology works for over 20 years, pulling apart my own devices, searching for solutions late at night, refusing to leave a problem unsolved. That curiosity became a career in Support, and more recently, a hands-on path into DevOps and cloud infrastructure.

9+ years in high-availability environments. Currently building and shipping things in production on Azure: CI/CD with GitHub Actions, Terraform, Prometheus, Grafana, Docker. The full stack, not just the theory. Open to relocating to Portugal, I already hold a Portuguese NIF and qualify for the D3 Tech Visa. Looking for opportunities in Support, SRE or DevOps.
