Back-end developer focused on Java and the Spring Boot ecosystem.

I build RESTful APIs applying clean architecture, good practices, and clear documentation.

I have hands-on experience with:

- Content Negotiation, DTO mappers (MapStruct) and pagination/search

- JPA/Hibernate for entity relationships and persistence

- Database versioning with Flyway

- File upload/download, including Excel data import/export

- Report generation with JasperReports

- Email sending workflows

- Testing with JUnit & Mockito

- Security with JWT authentication

- API documentation with Swagger / OpenAPI

- CORS handling and environments managed through Docker

- GitHub Actions for automation and AWS deployment

I work daily with tools like Postman, Git/GitHub, Maven, MySQL, and postgresSQL, keeping development workflow clean, consistent, and maintainable.

Currently seeking opportunities as a Java Back-End Developer, building efficient, secure, and scalable solutions while continuing to evolve within the Spring Boot ecosystem.
