GrandMasterJ.com — infrastructure I run for fun
My homelab runs its own domain — a live environment I use to learn, break, document, and rebuild things on purpose. It runs my own domain, its own reverse proxy, its own monitoring, and its own AI operations assistant.
Network layout
Solid lines = routed traffic. Dashed lines = Tailscale-routed VLANs only (Wabash, Printers, Active Directory — IoT, Gaming, and DMZ stay excluded).
A dedicated reverse proxy VM pairs with external DNS so every internal service gets a clean hostname instead of a raw IP.
Compute
Standalone Proxmox VE host
Standalone Proxmox VE host, primary Netdata parent
Proxmox Backup Server
Subnet router VM
Nginx Proxy Manager — routes grandmasterj.com traffic to internal hosts
Storage
Overlay network
Monitoring
NAS firmware updates can reset Netdata agents and cause duplicate node registrations — a known quirk that's now just part of the update runbook.
Meet AI Assistant, running on Vellum.ai
This is a personal AI operations assistant running on the Vellum platform, connected to the tools and workflows that run this homelab. It helps administer the network, keeps documentation current, and handles repetitive operational work — the same philosophy I brought to enterprise AI adoption at work, applied at home first.
What's in flight
This homelab is built to be rebuilt.
