Preston Bernstein — Full-Stack Developer, Home Lab & AI Agent 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: LightRAG, Ollama, and Claude Code agents that build and deploy alongside me.

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:

What a $364 Claude Code session taught me about running agents unattended
Three failure modes wearing one name: running concurrent Claude Code agents
Tuning LightRAG ingestion concurrency against a rate-limited Gemini API
Not every Docker container belongs on the NAS
