Back to original languageAbout Yorick
I build and evolve critical applications in a Java/Spring/Angular environment, with a dual role as a full stack developer and technical lead. My guiding principle for over 9 years: modernizing existing systems, securing production deployments, and elevating the technical skills of teams in demanding contexts.
My career has led me to work with BNP Paribas Personal Finance, Natixis, Orange, Air France, Canal+, and Enedis, on topics ranging from Java backend and REST APIs to Angular, Ionic, Kafka, continuous integration, and application architecture. I have worked on both internal business applications and high-stakes interconnected services, with sensitive production environments and strong quality constraints.
At BNP Paribas Personal Finance, I technically led developments around customer service and the person repository, in a modernization context towards IBM Cloud. Since 2024, I have also been involved in the RCLU project, designing a hexagonal architecture, implementing Kafka Stream/Connect flows, supervising technical choices, leading code reviews, supporting developers, and monitoring production deployments.
I rely on a solid foundation in Java, Spring Boot, Angular, Ionic, Kafka, CI/CD, unit and integration tests, with a constant focus on maintainability, best practices, and delivery quality. Mentoring is also part of my approach, in line with my role at OpenClassrooms.
I am particularly comfortable in contexts where it's necessary to take over an existing system, clarify the architecture, make flows reliable, and structure team practices. If you are looking for a lead developer capable of contributing technically while framing quality, architecture, and developer support topics, let's talk.
