Full stack by training,
engineer by practice.

I'm a full stack developer in Parnamirim/RN and have been working professionally in web development since 2022. Today I work at IMD/UFRN – GERTEC on remote access to payment terminals, aiming for performance, stability and a good experience for the people who use it.

Before that, at CDA Distribuidora, I maintained and evolved a corporate platform for commercial agreements and fleet control integrated with the ERP, automating processes with Spring Boot, React, Python and Oracle.

I hold a bachelor's degree in Information Technology from UFRN and am studying Software Engineering at the same university. I like building reusable components and encouraging good engineering practices on the team.
