Back to original languageAbout Yannick Michel
Systems & Network Administrator specializing in Windows / Linux, I help SMEs secure, modernize, and optimize their infrastructure.
I design, deploy, and maintain complete environments: Active Directory, Windows Server 2025, virtualization, backups, monitoring, Intune, Autopilot, Entra ID, network, and security.
My added value: a rigorous, documented, and service continuity-oriented approach.
Each mission is carried out with transparency, clear communication, and respect for the Malt framework.
Project examples:
• AD / GPO / AGLDP deployment
• Infrastructure migration or modernization
• Intune / Autopilot / WUfB setup
• Linux servers (GLPI, Wiki, Apache, internal services)
• Hyper-V / Proxmox virtualization
• Veeam backups & Nagios / Elastic monitoring
• Network security (VLAN, firewall, VPN)
Available for remote work or on-site (Nice + 50 km).
I work directly only, without subcontracting, in accordance with the Malt charter.
