About Charles

Passionate about the energy transition and data, I operate at the intersection of technical project management and business development.

My professional background has allowed me to support public and private stakeholders in digitizing their energy performance through the SaaS platform N’Gage, from technical design to commercial valorization.

🔹As a Project Manager, I have led complex multi-site deployments, orchestrated the integration of energy data (IoT, BMS, API), and supported users in change management.
🔹As a Pre-Sales Manager, I have bridged the gap between business needs and technical feasibility, designing high-value demonstrations and POCs, while managing a team of pre-sales engineers.
🔹As an Account Executive, I have developed the client portfolio in public and industrial markets, led complex sales, and signed structuring partnerships.

Curious, rigorous, and solution-oriented, I enjoy transforming data into a lever for efficiency and helping organizations reduce their energy footprint while gaining agility.
