À propos de Jean-Philippe

Vous avez besoin d'une application web robuste, d'un tableau de bord métier, ou d'automatiser des processus qui vous font perdre du temps ? Je conçois et développe des solutions sur mesure, de l'architecture à la mise en production.


25 ans d'expérience full-stack — des plateformes d'entreprise gérant des deals à plusieurs millions de dollars aux applications mobiles déployées pour 100M+ utilisateurs. Je travaille en remote depuis toujours, en mode asynchrone et autonome.


Ce que j'apporte : une vision produit (pas juste du code), un workflow augmenté par l'IA pour livrer plus vite, et une communication claire en français natif.


Projets types : applications Vue.js/React, APIs Node.js, intégrations tierces (CRM, ERP, paiement), dashboards avec visualisation de données, automatisation métier, audit et refactoring de code existant.
