What I'm looking for

I am looking for backend/Java roles focused on microservices and APIs, with collaborative teams, strong testing and CI/CD, and opportunities to grow technically.

I am a Java software developer with over six years of hands-on experience building backend systems, microservices, and registries for public and private sector projects. I have delivered production services using Java 8–17, Spring Boot, JPA/Hibernate, and relational databases while working remotely and in cross-functional teams.

I have driven feature development, data model changes, REST API design, integration fixes, and performance improvements across projects such as document/matter management, file storage, and decision engines. My work emphasizes test coverage (JUnit5, Mockito, JaCoCo), robust CI/CD practices, and containerized deployments with Docker and Kubernetes.

I am motivated, quick to learn, and experienced in tooling and practices that enable reliable delivery—IntelliJ, Git/GitLab/Bitbucket, Maven/Gradle, Liquibase, Postman, and observability tools like Kibana. I hold academic scholarships for achievement and bring a pragmatic, quality-focused engineering approach.
