Infrastructure automation, network services, and practical open-source tooling

About

I am Mark, a Bachelor Professional in Information Technology from Germany with a focus on reliable infrastructure, network services, and maintainable automation. I build tools and self-hosted systems that make complex technical workflows easier to operate and understand.

My work combines hands-on infrastructure experience with a strong interest in clear interfaces, reproducible setups, and useful documentation.

Areas of focus

  • Linux infrastructure and containerized services
  • DNS, networking, reverse proxies, and security
  • Shell scripting and operational automation
  • Go, React, and TypeScript applications
  • Technical documentation and knowledge sharing

Selected projects

RootGuard · rootguard.foxly.de

A self-hosted DNS appliance combining AdGuard Home with a hardened, DNSSEC-validating recursive Unbound resolver behind a guided, authenticated WebGUI — no manual Docker or config-file editing required. Public pre-release alpha, published as versioned, digest-pinned multi-arch images.

AdGuard Home Updater

A safe, automated updater for bare-metal AdGuard Home installations. It provides architecture detection, version checks, backup and rollback support, dry-run operation, DNS health checks, and systemd integration. Installation instructions are available at install.foxly.de.

dockerinstall

A standalone shell tool for installing, upgrading, validating, backing up, and uninstalling Docker Engine on supported Debian and Ubuntu systems. It supports interactive use as well as predictable automated provisioning.

dotfiles

A curated collection of shell scripts, server configurations, Docker templates, and operational tools used across homelab and server environments.

foxly-motd

A fast, updateable message-of-the-day system dashboard for Debian and Ubuntu, giving an at-a-glance system overview on login.

Engineering principles

  • Prefer transparent systems over hidden complexity.
  • Automate repeatable work and keep manual recovery possible.
  • Treat documentation as part of the product.
  • Build for maintainability, not only for the first deployment.
