I build, break, and document computers at home.

I’m Arthur Sommer, a DevOps engineer at Electronic Theatre Controls (ETC) by day. This is my home directory for homelab notes, open-source projects, practical guides, and field reports from running an unreasonable amount of infrastructure for one household.

System status

Current work

Custom Caddy modules, certificate automation, observability, resilient storage, and making the system easier to understand tomorrow than it was yesterday.
