About Alexis

Systems and network integrator, I intervene to deploy, administer, and secure IT infrastructures for companies — from Norman SMEs to large organizations.

My core business: installation and configuration of network and system infrastructures (Windows Server, Linux, Active Directory, virtualization, switching, routing), with systematic attention to the security of existing systems.

What sets me apart: I built my technical experience in a demanding industrial environment, through an apprenticeship at Knorr-Bremse — a global player in braking systems. In this high-criticality context, I learned what "availability" and "reliability" truly mean. An infrastructure failure can halt a production line. I apply this culture to every mission.

What I do concretely:
— Infrastructure integration and deployment (LAN, WAN, WLAN, VPN, VLAN, patch panel)
— Windows Server and Linux system administration (AD, DNS, DHCP, GPO, PKI)
— Virtualization (VMware ESXi, Proxmox, Hyper-V)
— Infrastructure security (auditing, hardening, firewalls, network segmentation)
— Monitoring and operational maintenance
— Consulting, technical audit, and team training

Profile:
Currently pursuing a Master of Engineering in Systems & Networks. Full educational path: BAC Pro Digital Systems → BTS SIO SISR → Network Security Bachelor's Degree → Master's in progress.

Availability and service area:
Based in Caen (14000). On-site intervention in Normandy, long-term missions in France possible. Remote work native.
