Loïc Lorente

Systems and network administrator, I support VSEs, SMEs, web agencies, and freelancers in making their IT infrastructure reliable, secure, and monitored, in both Linux and Windows environments.

I work on server administration (Debian, Ubuntu, Windows Server 2016 to 2025), virtualization (Proxmox VE, VMware ESXi, Hyper-V), infrastructure services (Active Directory, DNS, DHCP, GPO, Microsoft 365), storage and backup (Synology/TrueNAS NAS, replication, 3-2-1 strategy), as well as networks and security (pfSense and FortiGate firewalls, VLANs, IPsec/WireGuard/OpenVPN VPNs, CIS/ANSSI hardening, MFA, IDS/IPS). On the monitoring side, I deploy GLPI, Zabbix, and Grafana with log centralization, to move from a reactive IT approach to controlled and proactive operations.

What sets me apart: a rigorous and documented method. Each intervention is based on a prior backup, a rollback plan, step-by-step procedures, and as-built documentation (diagrams, runbooks, inventory). Security and traceability are prerequisites, not options.

Typical missions: infrastructure deployment and migration, setting up monitoring and backup, security audits and hardening, network segmentation, virtualization, and recurrent operational maintenance (MCO).

Preferring remote and fixed-price missions, I deliver reliable, secure, and sustainable solutions, accompanied by the necessary documentation for your autonomy.
