Jesús Javier Ágreda Algarra

I’m a Senior Backend Developer focused on building reliable, high-performance microservices with Java. I work with REST and “API-First con Swagger,” combining reactive patterns with solid architectural foundations like hexagonal architecture and DDD.

In my recent role at Métrica (Madrid), I develop “Microservicios REST con Java reactivo (arquetipo Darwin/Spring), JPA + Hibernate” and data access with “Oracle SQL / PostgreSQL.” I’m responsible for CI/CD using “GitHub Actions,” deploying on “Kubernetes / OpenShift,” and maintaining quality with “SonarQube” plus “JUnit + Mockito.”

At Sobremi EqTic (Barcelona), I deliver microservices with “Spring Boot y Spring Security,” and build event-driven systems using “Apache Kafka” and high-performance “ActiveMQ.” I apply “SOLID como base real,” leveraging “hexagonal architecture, DDD” and actively migrating pipelines “de Jenkins a Kubernetes” with “Google Cloud Platform” in mind.

Earlier, at Accenture (Alicante), I supported full-stack development for the “Ministerio de Sanidad,” working with “Java 11/17 + Vue.js,” “Spring Boot,” and a Scrum process. I also gained strong delivery experience at Serbatic (Cuenca) with “webs y REST / API-First,” covering “Thymeleaf,” “MongoDB,” “PHP,” and “HTML/CSS/JS,” and I adapt quickly to any team.
