👋 Bienvenue, Welcome !

Responsable de projet SI et développeur avec plus de 20 ans d'expérience couvrant les systèmes d'information, les télécoms et le développement logiciel. Ancien fondateur et directeur technique d'un SARL spécialisé dans l'hébergement web, VoIP SIP, infrastructure datacenter et réseau, puis responsable de projets sur le SI OSS de SFR, où je pilote des équipes de développement et des budgets de grande envergure. Double compétence rare : pilotage de projets complexes et maîtrise technique concrète — PHP (Laravel / Symfony), architecture applicative, bases de données, API et DevOps. Reconnu pour ma rigueur, mon autonomie et ma capacité à mener des projets stratégiques de bout en bout, du cadrage jusqu'à la mise en production et au maintien en condition opérationnelle.
