About Thomas

J'interviens en tant que Développeur senior sur des projets backend exigeants.

Ce que je fais concrètement

Architecture et développement backend PHP/Symfony (APIs, systèmes scalables, refacto legacy), lead technique et montée en compétence des équipes, et mise en place de pipelines d'automation IA avec n8n, Claude Code et les LLMs — pour réduire les tâches manuelles, accélérer les workflows, et produire plus vite sans sacrifier la qualité.

En parallèle, je construis mes propres produits SaaS. Ça veut dire que j'arrive avec une mentalité de builder : je comprends les contraintes produit, les enjeux de temps-to-market, et je prends des décisions techniques qui servent le business — pas uniquement l'architecture idéale sur papier.

Là où je suis le plus utile :
  • Startups et scale-ups qui ont besoin d'un lead technique opérationnel, sans recruter en CDI
  • Équipes avec de la dette technique legacy à moderniser
  • Projets qui veulent intégrer l'IA dans leurs processus (generation de contenu, automation de workflows, agents)
10 ans d'expériences sectorielles : assurance, immobilier, santé, transport, legaltech.

Thomas a un excellent niveau. Il a repris un code existant pour le rendre encore plus performant. Il travaille avec l'objectif d'avoir un produit plus facile à maintenir et développer. C'est un plaisir de travailler avec Thomas.
