Name: Rolf
Role: Linux / Infrastructure Engineer

I'm a Linux and infrastructure engineer working with enterprise Linux, virtualization, automation, containers and increasingly AI/GPU infrastructure. Xnett.org is where I document things I build, problems I solve and technologies I find interesting.

cat /etc/xnett/README

Xnett is the name I build under. It covers the writing on this site and the software behind it: open-source tools for Linux and containers, a family product in development, and a custom platform that runs a small business in production. Each project keeps its own name and look. Xnett is the common thread, not a company with a team.

Xnett.org/This site — a self-hosted Next.js + Postgres CMS running in Docker behind Caddy.

cat /etc/xnett/homelab.conf

Two Proxmox nodes, two Docker hosts, a NAS, UniFi from gateway to access points and one GPU laptop. Home Assistant, Jellyfin, Nextcloud, the *arr stack, local LLMs and my own Ops Center run here — the practical proving ground for most of what ends up written about here. Start with "My homelab, top to bottom" under /homelab.
