About Grégory

With 20 years of experience in information systems, I have evolved through various strategic roles. My mission? To boost SMEs and administrations by modernizing their information systems.

I see my clients as allies. Their success reflects mine, which is why I adopt an entrepreneurial vision, key to seizing and supporting their strategic ambitions. Whether in the development of IT infrastructure or applications, my goal is to propel them to a higher level.

Versatile, I manage IS governance, develop strategies, manage IT budgets, and can even assume the role of part-time CIO/CTO. As an expert in transition management, I excel in IS auditing and mapping, project management, change management, and service provider supervision. In architecture and operations, I select relevant tools, lead technical infrastructure deployments, and ensure optimal service quality.

My motto? To use cutting-edge technology to maximize the efficiency and satisfaction of our partners and their clients, always aiming for excellence.
