What I offer
Three ways to work together
As a consultant or a full-time hire, this is where I bring the most value.
Java & Angular applications
Design and development of business-critical applications with Java/Spring Boot and Angular, built to last and stay maintainable.
Sectors: pensions, insurance, banking (La Cipav, GMF, Barclays).
DevOps & AWS Cloud
CI/CD pipelines, Docker/Kubernetes containerisation and migration to AWS, to ship more often and with more confidence.
At Barclays: CI/CD, containers and the move to AWS.
Experience
12 years, from code to leadership
Banking, insurance, social protection: projects where reliability matters.

Aug 2023 — present
Technical Lead · La Cipav
I lead the technical side of GDP (Person Management), a strategic project at La Cipav, the pension fund for France's liberal professions. I manage a team of 5+ developers and own the architecture: a Java 21 / Spring Boot 3 back end in three modules (REST services, business logic, batch jobs) and an Angular 21 front end. Since late 2023: 50+ releases, around fifteen automated data flows with partners (SNGI, RNCPS, URSSAF, La Poste, DILA…), and a GitLab CI pipeline that tests, analyses and ships every component as a Docker image.
