• Orange Bank: Developed microservices with Java + Spring Boot. Stepped up as acting Tech Lead for the Bizum microservice, ensuring delivery, architectural alignment and mentoring the team.
I combine hands-on development with technical leadership and mentoring, ensuring both delivery speed and long-term maintainability. My expertise covers:
• Architecture: DDD, Hexagonal, Clean Architecture, event-driven systems
• Cloud & DevOps: AWS (EKS, Lambda, SQS, S3), Docker, Kubernetes, CI/CD with GitHub Actions & Jenkins
• Quality: TDD, XP, automated testing (JUnit5, Testcontainers, WireMock)
I thrive in agile teams, helping developers grow, promoting clean code and solid engineering practices, and aligning technical solutions with business goals.
