What I'm looking for

I am interested in Junior Java Developer opportunities where I can contribute my existing technical experience, continue learning and grow as a backend developer.

I am currently strengthening my Java fundamentals and backend development skills, with a particular interest in software design, automated testing and building reliable applications.

Through personal projects, I am gaining hands-on experience with Java, Spring Boot, Spring Data JPA, MySQL and REST APIs. My current project is a product management API that includes CRUD operations, DTOs, input validation and centralized exception handling.

At DefineTec, I provided technical support for data flow and billing applications in telecommunications environments. I troubleshot databases, implemented corrective actions, and participated in application implementation and deployment activities.
