About Mattieu

Systems administrator with 4 years of experience, including 2 years in a Secret Defense environment — where rigor is not an option.

What I manage for you:
— Active Directory Administration (accounts, GPO, permissions, security)
— Microsoft 365 tenant management (Exchange Online, Teams, SharePoint, Intune)
— Azure Administration (VMs, storage, Azure AD / Entra ID, security)
— Deployment and compliance of workstations via Intune / MDM
— L2/L3 support in full autonomy

My approach:
I quickly take charge of your IT environment, document everything, and deliver cleanly. Accustomed to high security constraints, I work with the same level of requirement on every mission.

Stack: M365 · Azure AD · Active Directory · Windows Server · Intune · PowerShell

100% remote. Available quickly. Documentation delivered with each mission.

AZ-104 Certification (Azure Administrator) in preparation.
