About

I'm David Cruz. Backend engineer by day, homelab tinkerer + AI-substrate builder by night. This site is where I dump the notes I'd want to find myself if someone else had written them first.

Expect posts on: Proxmox, Kubernetes (Talos), Cloudflare Workers/D1, LLM plumbing, cheap-but-load-bearing distributed systems, and the occasional detour into whatever I've been rebuilding this week.

Written by a human. Sometimes with a robot looking over his shoulder. Both of us stand behind the code samples.
