Description

Software development professional with over 6 years of experience in the Java ecosystem, working on Maven and Spring-based projects. Solid track record in designing, developing, and maintaining backend applications, with a special focus on building robust, scalable, and resilient solutions in distributed environments.

Experience in enterprise environments, participating in both the development of new functionalities and the evolution and modernization of existing systems. Regular work with microservices architectures, applying SOLID principles, TDD, and clean/hexagonal architecture approaches to ensure quality, maintainability, and decoupling.

Specialization in systems integration and asynchronous processing using messaging (Apache Kafka), as well as in the development of well-defined and documented REST APIs (OpenAPI/Swagger). Experience in reactive programming with Project Reactor and in the efficient design of data access in both relational (PostgreSQL, MySQL) and NoSQL (MongoDB) databases, using Spring Data.

Familiarity with modern development and operation practices, including version control with Git, testing (JUnit 5, Mockito, integration tests), containerization with Docker, and continuous integration and deployment (CI/CD with GitHub Actions, GitLab CI, or Jenkins) pipelines. Knowledge in system observability through logging and metrics (ELK, Prometheus), facilitating monitoring and diagnostics in production.
