From Code of Law to Code of Software.
Portuguese-Brazilian IT professional based in Portugal, transitioning into software development after nearly a decade as a lawyer in the oil & gas regulatory area. I build full-stack, cloud-ready web applications, with a strong focus on Java and modern web development.
The Career
Pivot
Full Stack Developer
Building modern applications with Java/Spring concepts, JavaScript tooling and cloud-ready deployment patterns. Experience collaborating in Agile environments (Azure DevOps) and supporting integration/data migration workflows (MuleSoft).
Deconstructing Logic
Transitioned full-time into software development. Focused on Java, OOP and modern web development while building full-stack projects and strengthening my cloud fundamentals. Worked for nearly 5 months at NTTData, one of the largest IT consultancies in the world.
The Jurisprudence Era
Practiced law leading regulatory work in oil & gas. That experience sharpened my analytical thinking, attention to detail, and ability to reason through complex constraints — skills I now apply to software engineering.
