Systems Operator in a 24/7 Security Operations team, working on critical government infrastructure real-time monitoring, incident detection and response, and on-call rotations. Alongside the day job I'm going deep into offensive security: pentesting, Active Directory and Linux, and a self-hosted lab where I break things on purpose.
I like understanding systems from the inside — how they run, where they fail, and how an attacker would abuse that.
Now → Security Operations · monitoring & incident response (24x7)
Specialising → Pentesting · Active Directory & Linux
Building → Self-hosted homelab · LivingLinked (Laravel app)
Next → eJPT → CRTO → OSEP
Not a badge collection. A running multi-node lab I administer end to end.
Proxmox cluster
├── Node A · X99 dual Xeon → main compute, VMs & LXC
├── Node B · Z370 → secondary node
├── MikroTik CRS326 → segmented network with VLANs
├── Pi-KVM (Raspberry Pi) → out-of-band management
├── NAS (6× HDD) → backups
└── Remote access → Tailscale / WireGuard (zero exposed ports)
Skills this proves: Linux administration · virtualisation · network segmentation · VPN & remote access · backup strategy · service self-hosting.
