🎉 Projects & Hobbies

RKE Kubernetes cluster owner, two startups member, DevOps… a lot of DevOps.

Skatepark, kindergarten, and workout design/building — DevOps for the real world.
Local newspaper design and publishing; wedding cameraman; occasional philanthropist.
Built 100+ websites; created microcontroller hardware; open‑source contributor.

🔥 Roast Me

If infrastructure is code, mine is probably over‑engineered enough to file for an art grant. I promise it’s on purpose. Mostly.

I speak fluent YAML, occasionally to my coffee machine. Side effects include reliable platforms, smug dashboards, and the inability to explain my job to relatives.
