I build backend systems and write down what actually happens while building them.

Day to day that's Spring Boot and Laravel at Hargassner, alongside a CS degree at TU Wien. The same instinct applies to my own infrastructure outside of work — a homelab rebuilt to be reproducible with Ansible, and the Linux and privacy questions that come with running it.

Now

Rebuilding the homelab on Ansible, and studying for the CS degree at TU Wien.

Self-hosted homelab on Ansible

A self-hosted service stack — Caddy, Uptime Kuma, Nextcloud, Immich, SimpleLogin and ntfy, with restic backups to a Raspberry Pi — rebuilt on Ansible instead of configured by hand.

Why. Every config in one place, versioned, and tested on a throwaway VM before it reaches production.
