About Vincent

Tech Lead Javafreelance, **12 years of experience**. I join your teams to structure your high-stakes projects, secure your architectural choices, and advance your developers.

My profile in **three points**.



**Technical Expertise**. High-performance Java / Spring backend architecture, API and platform design, critical and scalable applications. I notably led a Java product deployed in 6 countries at Leroy Merlin: architectural decisions, CI/CD, DevSecOps, code reviews.



**Product Vision**. I designed and launched my own SaaS products from A to Z (Ekurie, Prospectly, VIPIT). I link every technical choice to a business objective and prioritize what creates value.



**Teaching**. I don't force my way, I transmit. I explain the why behind decisions, I encourage the adoption of best practices, and I leave your teams more autonomous than when I arrived. This is also my role as a Java mentor and evaluator at OpenClassrooms since 2023.


I integrate AI into my workflow to deliver faster, without compromising on quality, review, or security.

**On assignment**: technical scoping, architecture, application and API development, audit and refactoring, team support and skill development.
