🔥 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.
