Frederic Lala

Systems and infrastructure administrator specializing in Linux environments and cybersecurity, I help VSEs, SMEs, and technical teams deploy, secure, and maintain reliable infrastructure, without depending on a large provider.

I have independently managed the infrastructure of a site hosting about fifty internal users, its members, and the public during events: Proxmox virtualization (VM and LXC), UniFi network segmented into VLANs (28 switches, 100 access points), 3-2-1 backup rule, internal PKI, and security hardening. I have also deployed ANSSI-approved air-gapped cyber backup solutions for VSE/SME clients.

Specifically, I can remotely handle:

Installation, administration, and hardening of Linux servers (Debian/Ubuntu)

Proxmox virtualization and migration, including VMware exits

Deployment of containerized solutions (Docker, Docker Compose)

Reliable and tested backups (Proxmox Backup Server, ZFS, 3-2-1 rule)

Network, VLANs, DNS, VPN, and monitoring (Zabbix, alerting)

Self-hosting of open-source solutions (Nextcloud, Passbolt, Immich, n8n)

I work remotely, autonomously, with a focus on clear documentation and simple, long-term maintainable solutions. Whether for a one-time mission (audit, installation, migration) or regular support, I adapt to your needs and explain what I do without unnecessary jargon.
