I’m Preston Bernstein, a full-stack developer based in Atlanta, GA, with over a decade of experience across front-end and back-end work. My professional focus is building and optimizing web applications; my off-hours focus is the infrastructure underneath them.
What I work on#
My home lab is the test bed for most of what appears on this blog:
- Infrastructure and networking. A Synology NAS, a desktop workstation, and a retired Dell XPS 17 running Proxmox VE, behind a UniFi gateway and switch with Pi-hole DNS filtering.
- Self-hosted services. Media automation, family photo backup with Immich, and a placement framework for deciding which containers run where, with Prometheus and Grafana observability shared across all of it.
- AI engineering. Knowledge-graph retrieval built on LightRAG, and local LLM and vision-model inference through Ollama on a single shared GPU.
