About Eric

With over 20 years of experience in information system management, from definition to operation,
I have a good command of activity and multi-site team management, as well as subcontracting supervision.
Accustomed to managing internal and external client relationships, analyzing requests, and potentially re-qualifying them.
In recent years, I have focused on auditing and reverse engineering projects, as well as rationalizing and managing obsolescence of IT and network infrastructure and resources.
Securing production platforms and cybersecurity.
