Gabriel Neves Ferreira da Rocha

Summary

Developer interested in back-end, systems and software engineering. I build applications and APIs with different stacks depending on the problem — Java and Spring Boot, Python and Django, and C for systems programming. Hands-on experience with relational databases, automated testing, documentation and continuous deployment (Docker and GitHub Actions). Currently pursuing a Computer Science degree at CESAR School, seeking a first professional opportunity.
