Preston Bernstein — Full-Stack Developer, Home Lab & AI Engineering

I’m Preston Bernstein, a full-stack developer in Atlanta with over a decade building and running web applications and the infrastructure under them.

Most of it comes out of my home lab: a Synology NAS, a GPU desktop, a retired laptop running Proxmox VE, and self-hosted services like LightRAG and Ollama.

The blog covers home-lab infrastructure and networking, self-hosted service observability, and AI/LLM engineering, including the debugging sessions that didn’t go cleanly.

A few places to start:

Fifteen of eighteen root causes I was sure about were wrong
It took nine fixes to stop a LightRAG crash
My GPU broker kept killing inference jobs for games that weren’t running
Not every Docker container belongs on the NAS
