Description

Tech Lead & Software Engineer | Java/Spring Boot | Architecture & Craftsmanship

Tech Lead and backend developer with 9+ years of experience, delivering high-stakes technical projects for major enterprise clients: Société Générale, Crédit Agricole, Groupe Pomona, La Poste Group, and Orange Labs.

I specialize in designing and building robust applications using Java/Spring Boot, hexagonal architecture, microservices, and craftsmanship practices (TDD, BDD, clean code). I also bring strong hands-on expertise in CI/CD, DevOps (Docker, Kubernetes, Jenkins, GitLab, Ansible), and cloud environments (AWS).

Beyond development, I lead and coordinate cross-functional teams — developers, architects, infrastructure — and own key technical decisions: architecture design, legacy migration, monitoring stack setup (ELK, Dynatrace), and network/environment provisioning.

I am also a trainer: throughout my career, I have consistently coached and trained developers through hands-on workshops, code reviews, and dedicated training sessions on Spring Boot, testing strategies, and software architecture.

Available for technical consulting, or training missions — remote or hybrid.
