What I'm looking for

I seek a hands-on backend role focused on Java/Spring Boot and REST APIs in a collaborative, learning-oriented team with growth opportunities.

I am a proactive Junior Backend Developer with a Higher National Diploma in Multiplatform Application Development (DAM) and hands-on experience building Java Spring Boot backends, designing REST APIs, and implementing data persistence with JPA and SQL. During a DAM internship at Bluemara Solutions S.L., I contributed to backend features, implemented unit tests with JUnit and Mockito, and used Git/GitHub for version control.

My background also includes strong technical support and audiovisual engineering experience, which cultivated teamwork, adaptability, and performance under pressure. I seek to apply my solid foundation in Java, Spring Boot, testing, and APIs to contribute to backend projects while continuing to grow technically through real-world challenges.
