About Geoffrey
Ingénieur logiciel Senior IA - 8 ans
Pour startups et scale-ups SaaS B2B, je transforme des problèmes métier complexes en produits web fiables et maintenables :
la technique doit servir le business, pas l’inverse.
Chez Ondorse, un SaaS de conformité KYB/KYC, j’ai transformé des développements ad-hoc nécessaires à la signature de grands comptes en outils no-code internes : éditeur de workflow et de règles de conformité. Résultat : les équipes Customer Success peuvent onboarder et construire la politique de conformité d’un client en 2 jours au lieu de 2 semaines, sans dépendre de l’équipe tech.
Chez ManyPixels, j’ai co-fondé et construit de 0 à $65k MRR en 1 an une plateforme tout-en-un : onboarding clients, abonnements, stockage, chat et dispatching des tâches designers.
Les services que je vous propose :
🔍 Auditer un produit, son UX et son architecture
J’identifie ce qui limite la valeur d’un produit : frictions UX, parcours trop complexes, dette produit, architecture fragile, performance, sécurité ou maintenabilité. Je transforme cet audit en plan d’action clair : ce qu’il faut corriger, dans quel ordre, et pourquoi.
🚀 Porter une feature ou un produit de 0 jusqu’à la production
Je prends l’ownership complet d’un sujet : problème client, cadrage, arbitrages, architecture, développement et mise en production.
🔧 Reprendre et fiabiliser des applications “vibe-codées”
Je reprends vos prototypes construits avec Cursor, Lovable, v0, Bolt en applications maintenables : architecture claire, standards de développement, typage, sécurité, gestion des erreurs et dette technique maîtrisée.

🧭 IA assistée, gouvernance humaine
L’IA au quotidien en tant qu'assistant, pas un pilote : je garde la responsabilité des choix techniques, de la qualité et de la sécurité du produit.
