Message

At ESAB – Escola Superior Aberta do Brasil, I developed, maintained, and evolved corporate web applications using Java and VRaptor4. I also implemented new features and fixed issues in existing systems.

I worked with PostgreSQL queries and system integrations, and maintained application communication features. My work also included MVC applications with Hibernate and monitoring deployments in Apache Tomcat 8.

I participated in code versioning with Git and compilation and deployment processes using Maven and Jenkins. I also developed and maintained reports with JasperReports/iReport and monitored applications hosted on AWS infrastructure.

Before moving into Java development, I supported academic and administrative processes at ESAB and provided IT support at IFES and Estevão Tecidos. Since November 2023, I’ve worked independently as a driver for digital platforms.
