About me

My background, experience, and how I approach software development.

Hi, I'm Tomas Gabriel Cardozo. My path into software started in operations, administering SQL Server databases and keeping internal systems running at Grupo Serin. Fixing real production problems, not just studying them, is what pulled me toward backend development.

Since then I've built and maintained Java and Spring Boot systems in production: migrating a legacy Symfony backend to Spring Boot, and optimizing SQL queries that cut execution times from hours to seconds. I care about clean architecture and secure APIs, code that holds up under real usage, not just in a demo.

I'm now deepening my skills in microservices and Docker, and I enjoy agile, remote teams where I can turn business requirements into stable, scalable systems.

Experience

Real roles where I delivered on development, performance, and systems.
