Back to original languageAbout Mohamed
Freelance systems & networks engineer with over 8 years of experience, I support companies in the design, administration, security, and optimization of their IT infrastructures.
I work on complete environments combining servers, networks, virtualization, security, remote access, backup, and advanced support. My areas of expertise notably cover VMware, Proxmox, FortiGate, VPN, LAN/WAN, Windows Server, Linux, 24/7 monitoring, IT audits, technical documentation, and operational maintenance.
I have supported clients on various projects: network infrastructure overhaul, deployment of HA Proxmox clusters, implementation of secure VPN access for remote users, multisite technical support, infrastructure audit and improvement of operating procedures, or setting up private cloud.
My approach is pragmatic, clear, and results-oriented: quickly understand the existing situation, identify risks, propose reliable solutions, document properly, and ensure a stable, secure, and scalable infrastructure.
I can work as support for an IT team or independently on outsourcing, architecture, migration, security, or L2/L3 support topics.
Available for short or long missions, on-site or remote depending on the need.
