/homelab

• I enjoy tinkering with small technology projects, and I learn a ton from these experiments. I also self-host a number of apps/services from my home as well as various cloud environments. This page describes some of my technical playground.*

Everything is connected to my Tailscale [1] tailnet, with a GitOps-managed ACL to allow access as needed. This lets me access and manage systems without really caring if they're local or remote. Tailscale is magic [2].
