About Vincent

The problem I solve
You have a product to build, infrastructure to modernize, or a backend that can't handle the load. You're looking for someone who understands both code and business – not just an executor waiting for specs.

What I bring
8 years of experience in software engineering and DevOps. I design backend architectures in Go and PHP/Symfony, containerize with Docker/Kubernetes, automate deployments with Ansible and GitLab CI/CD, and implement monitoring from the start.

Concrete proof
→ Ouidrop (4 years): SaaS product built from scratch. Go + PHP/Symfony + Angular + MongoDB stack. Result: license sold for €25K/year/client, 2 funding rounds totaling €11M.
→ Invivox: medical training platform, backend and infrastructure overhaul.
→ FLOA Bank: banking environment, security and compliance constraints.
→ Total business value generated over my last 3 missions: ≥ €17M.

My method
I don't charge for time spent. I get involved in the product, propose solutions, and challenge specs when necessary. TDD, code reviews, documentation – the code I deliver is maintainable by anyone after me.
I use Claude Code (AI development) daily to accelerate deliverables without cutting corners on quality.

Conditions
→ Daily rate: €650/day
→ Location: Bordeaux metropolitan area for in-person, full remote otherwise (France and international)
→ Freelance only (VincsInsight company)
→ CII approved – your missions may benefit from the Innovation Tax Credit
