Acerca de José

I’m a software engineer specialized in backend development with Java and Spring Boot. I work mainly on enterprise applications, developing and maintaining REST APIs, system integrations, SQL queries, internal services, and process automation tools.

I can help with backend feature development, bug fixing, external API integrations, SQL optimization, backend code reviews, and technical maintenance of Java applications.

My experience includes Java, Spring Boot, JPA/Hibernate, Oracle SQL, Maven, Git, Swagger/OpenAPI, Feign Clients, MapStruct, and Lombok.

I focus on understanding the problem, providing practical solutions, and delivering clean and maintainable code.

I’m available for project-based work, hourly support, and backend maintenance tasks.
