About Pierre

Hello,

I help SMEs and associations migrate and modernize their IT infrastructure, particularly during the transition to Microsoft 365, the overhaul of a Windows Server environment, or the improvement of existing security and backups.

My goal is simple: to implement reliable, understandable, and easy-to-maintain solutions while minimizing user disruption.

I mainly work on:

Migration to Microsoft 365 (Exchange Online, OneDrive, SharePoint)
Windows Server and Active Directory Administration
Audit and improvement of existing infrastructures
Deployment and configuration of Windows workstations
Implementation of backup and secure remote work solutions
With over 10 years of experience in systems and networks, including technical responsibilities in demanding environments, I am involved in both the design and operational implementation phases.

In parallel to my technical missions, I also work as a trainer in systems and networks, which allows me to deliver documented and understandable environments for your teams.

I remain at your disposal to discuss your project and offer you a solution tailored to your structure.

Sincerely,
