01.About me

I work at General Motors in São José dos Campos, Brazil, building automation and integration solutions for more than 250 industrial processes. I use Java in supervision, monitoring and data analysis systems for production lines.

My main focus is the back end: I build REST APIs with Java 21, Spring Boot, Spring Security, JPA/Hibernate and PostgreSQL, running on Docker with Flyway migrations. On the front end, I work with React and JavaScript.

I hold an associate degree in Back-end Development and a postgraduate degree in Artificial Intelligence and Machine Learning, and I'm currently pursuing a bachelor's in Computer Science at UNIP.
