About Arnaud

Développeur Full-Stack senior avec plus de 15 ans d'expérience, je conçois des applications web performantes et j'automatise les processus métier grâce à l'IA.
Ce que je fais :
— Applications web complètes (React, Node.js, .NET) : interfaces utilisateur, APIs, back-office
— Automatisation de tâches avec n8n et Make : workflows, intégrations, agents IA connectés à vos outils
— Intégration d'APIs et connexion entre vos logiciels existants
— Architecture technique et conseil pour PME en transformation digitale
Mon parcours : 12 ans en tant qu'ingénieur technique senior dans un grand groupe international, où j'ai conçu, développé et maintenu des applications et des systèmes complexes. En parallèle, je me suis spécialisé dans l'automatisation et l'intégration d'IA dans les workflows métier.
J'apporte fiabilité, code propre et résultats concrets. Disponible en remote, réactif et autonome.
