What I do
Lead Dev / Backend Architect & Fractional CTO - 15 years on critical web platforms (supply chain, media, marketplaces). I code, I architect, I structure teams; on the advisory side, I step back once the ground is ready.
Two main types of missions:
- **Lead Dev / Backend Architect**: architecture refactoring, technical migration, platform building, technical leadership.
- **Fractional CTO / Tech Advisor**: to structure the tech before hiring an internal CTO. Audit, architecture choices, recruitment, processes (Scrum, CI/CD, code review).
Background
15 years of experience: 9 years freelance (Two Rings) + 2 years as CTO (Emploi Système in Luxembourg, then FoodMeUp) - team built from 0 to 8, Scrum, CI/CD, recruitment. Earlier: project manager at Theodo, marketplaces at Cocolabs (Cocorico/Symfony).
Recent missions:
-Orange OPTV— Senior Dev: multi-media 'control tower' OCS (Gframe, Elasticsearch). Stack modernization (PHP 7.4 → 8.5, MySQL → MariaDB 11.8 LTS), cache + indexing → response time halved.
-Meero— Senior Backend & PHP Lead: CI migration Jenkins → GHA, PHP 7.2 → 8, Symfony 5.1 → 5.4
-Shippeo— Senior Backend: real-time supply chain platform (Symfony, RabbitMQ, Algolia, Go)
-ADS/ALCOPA— Architect/Lead Dev (2.5 years): Symfony microservices + RabbitMQ + GraphQL, ELK, self-hosted Kubernetes, blue/green
