HPC Sysadmin
with a "rack"
in the corner.
I'm Robert — 10+ years of Linux, self-hosting, and infrastructure.
Cybersecurity background.
Still satisfying when it all just works.
The Rack
A full breakdown of my homelab in 2026 — Proxmox cluster, Talos Kubernetes, GitOps with Flux, and every service running in the rack.
Homelab Patching
A practical guide to keeping a multi-node Proxmox cluster, Talos Kubernetes, Synology, pfSense, and Docker services updated — rolling upgrade strategy, Renovate automation, and a cadence that doesn't consume your weekends.
Founded and ran CS 1.6 and Metin2 private servers alongside a gaming portal built on FreeBSD, Joomla and phpBB.
Managed Linux infrastructure on Debian with XEN, Kubernetes and Puppet — plus Asterisk VOIP and IPsec VPN.
Ran vulnerability assessments with Nessus and managed next-gen firewalls from Cisco, Fortinet and Palo Alto.
Deployed and maintained enterprise HPC clusters with PBS job scheduling, Salt configuration and Active Directory integration.
Practical writing on Linux, Kubernetes, HomeLab and security — built with Astro, open-source and self-hosted.
A digital agency building web projects end-to-end — from custom development to cloud and server management.
