About Me

I am Renato de Azevedo Caldas, a 21-year-old Systems Analyst intern in Rio de Janeiro focused on building enterprise software that improves operations through cloud, automation, backend development, and systems integration.

I study Computer Science at Veiga de Almeida University, with graduation expected in 2027, and I enjoy turning business requirements into reliable technical solutions for internal teams and production environments.
