Linux infrastructure for Mannheim, Rhein-Neckar, and beyond — small, stable, explainable.
I design and run Linux infrastructure and Docker environments in Mannheim. Hosting, publishing, IT security — and custom tooling when off-the-shelf products fall short.
From Proxmox and Docker to OPNsense and WireGuard, I document what works in practice. That includes monitoring with Grafana and Prometheus, and self-hosted services like Nextcloud and Jellyfin.

Focus topics for Linux, Docker, and secure infrastructure
These areas collect the practical core of this portfolio: Linux servers, Docker stacks, VPS operations, backups, monitoring, remote access, and security decisions for small, maintainable infrastructure in Mannheim and the Rhein-Neckar region.
The focus stays deliberately small, stable, and explainable: fewer open ports, clear documentation, testable backups, and infrastructure that still makes sense months later.
The focus is concrete operational detail: clean updates, understandable network paths, safe publishing, monitoring signals, and recovery steps that actually help in day-to-day maintenance.
