Senior Back End Developer · Spain
Available for new freelance projects · remote (EU time zones) or on-site
I'm from Archena, a small town in the Valle de Ricote, in the Región de Murcia, Spain — still home for me today. What pulled me toward backend engineering is the same thing that keeps me there: I like understanding exactly what happens to a request between the moment it arrives and the moment it leaves, and I care most about getting that right in the places where it matters — authentication and security chief among them.
At Capitole I work on OAuth 2.0 flows and customize Spring Authorization Server for Inditex's login platform — new login features, new flows, and the security work that comes with handling real users' credentials at scale. Before that, at CTT Express Paquetería Urgente, I built microservices for a logistics platform where resilience mattered as much as the business logic: Kafka, REST and SOAP holding a distributed system together under load.
Earlier, at Universidad de Murcia (TICARUM), my job itself was Sakai — Spring Boot and Spring MVC development, QA, deployment and maintenance for the open-source e-learning platform, done in collaboration with its wider community. It was my first real experience shipping code that other people actually relied on.
