What I'm looking for

I’m looking for a Java backend role focused on microservices (Spring Boot, REST APIs) with real production support. I want to keep systems stable and scalable, work with cross-functional teams, and grow in delivery and continuous improvement.

I’m a Backend Developer focused on building and maintaining Java-based solutions using JAX-RS, microservices architecture, and RESTful APIs. I work in production-critical environments, handling both maintenance and new-project delivery while keeping systems stable and performant.

In my current role as a Java Developer (Mid-Level) at Capgemini, I’m responsible for the maintenance, enhancement, and continuous evolution of microservices-based applications with Java and Spring Boot. I participate in new projects and provide production support, create and maintain technical documentation, and execute API integration testing to validate functionality across services.

Before that, I supported legacy systems and REST APIs at Lello Condomínios, performing API integration tests, functionality validation, and documentation. I bring a strong accounting and financial management background that helps me develop tech solutions with a solid business perspective, combining proactive teamwork and clear communication to deliver reliable results.
