Expert Symfony & Lead Dev — Integrating AI into my development processes
PHP/Symfony Developer for over 10 years, active contributor to the Symfony framework and official PHP documentation. I assist teams with critical migrations, platform stabilization, and performance optimization.
What sets me apart: I use AI (Claude, LLMs) as a concrete productivity tool — code review, refactoring, documentation — not as a gimmick. The result: faster deliveries, better-structured code.
My typical interventions:
- Symfony Migration (legacy → 7.x) with a progressive transition plan
- API architecture, microservices, performance optimization
- CI/CD, Docker, AWS setup
- Integration of AI/LLM into existing applications
Based in Lille, available remotely or on-site.
