What I'm looking for

I am looking for challenging projects where I can apply my skills and contribute to team success.

I am a back-end developer with over 3 years of experience, specializing in Java and the Spring ecosystem. I graduated in Systems Analysis and Development from FIAP, where I honed my skills in software development and testing. My expertise includes Java development using Spring Boot, Spring Security, and Spring Data JPA, ensuring quality and reliability in my deliveries through rigorous software testing.

Throughout my career, I have worked on various projects that involve microservices architecture and modern practices such as Continuous Integration and Continuous Deployment (CI/CD) with GitHub Actions and Jenkins. I am proficient in a wide range of tools and technologies, including RestAssured, Testcontainers, Maven, Git, RabbitMQ, Docker, and PostgreSQL. My commitment to delivering innovative solutions within deadlines has been a key factor in my success.

I am currently seeking opportunities to apply my skills in challenging projects and contribute to the success of a dynamic team. I thrive in collaborative environments and am dedicated to continuous learning and improvement.
