À propos de Jérôme
Ancien CTO, toujours développeur. Vous me confiez un projet, je vous le livre : cadrage, architecture, réalisation, mise en production.
J'ai construit des systèmes qui comptent : un programme national de dématérialisation de la procédure pénale, des applications métier à 60 000 utilisateurs/jour, une infrastructure distribuée supervisée 24/7. Et je les ai pilotés, roadmap technique, équipe de 7 personnes, budget.
Comment j'interviens :
• Projet de bout en bout : vous avez un besoin et personne pour le porter.
• Renfort d'équipe backend : livrer sur une roadmap chargée, en autonomie.
• Reprise en main de codebase : comprendre l'existant, stabiliser, faire évoluer.
• Architecture & performance : conception d'APIs, montée en charge, optimisation des bases et de l'infrastructure.
• Industrialisation : transformer un prototype ou une automatisation en service fiable : files d'attente, reprises sur erreur, supervision, coûts maîtrisés.
Stack : Node.js, TypeScript, PHP, PostgreSQL, Oracle, Docker, Kubernetes, CI/CD.
Je livre ce que je code : infrastructure, déploiement et supervision compris.
Disponible immédiatement, 100% remote.
