Back to original languageAbout Pierre-Alain
Experienced Java Developer and Lead Developer for over 10 years, primarily back-end, with a strong interest in Angular for the front-end. I support application transformation and modernization projects in industries such as pharmaceuticals, energy, and logistics. My expertise includes complex technical migrations (Java 7 → 21, Spring → SpringBoot, Sonic ESB → Tibco), setting up CI/CD pipelines (GitLab CI, Ansible), and deploying containerized solutions (Docker, Kubernetes).
Currently a Java Tech Lead at Relyens, I guide developers in evolving their tools and practices, such as implementing application monitoring and observability, and using Renovatebot for automatic dependency updates.
Throughout my experiences (Boiron, Biomerieux, EDF, Merck, FM Logistique, Relyens), I have demonstrated my ability to integrate heterogeneous systems (EBX, Salesforce, X3, Reflex), design robust solutions, and ensure the longevity of critical applications. Curious and pragmatic, I prioritize delivering quality code, transmitting best practices, and ensuring the robustness of pipelines for reliable and sustainable deployments.
