Back to original languageAbout Jean-Nicolas
Technical Product Manager with 10 years of experience in delivering critical platforms for industrial clients in France and internationally (energy, environment, manufacturing).
🔧 I have delivered 8 .NET applications used by 500+ users across 29 sites, integrated with complex business systems (ERP, batch, field tools). My deliveries include custom CRMs, simulators, rule engines, and configurable interfaces with dynamic validation.
🧩 Specializing in rigorous scoping and writing ready-to-code specifications (UX, API, business rules, edge cases), I optimize collaboration with developers and drastically reduce critical bugs in production.
💻 Former C developer (5 years at Murex), I understand code constraints, identify business blind spots, and secure deliveries without compromising robustness.
📍 Available for remote work, I work autonomously with SMEs or large corporations to scope, stabilize, and deliver structuring projects.
