Hi, I'm James

I'm a Technical Support Lead at Vero Networks, a fiber internet provider. At home I run a homelab and build the tools that keep it running, from monitoring agents to Linux desktop apps. I'm looking for systems administration, infrastructure engineering and agentic AI roles.

🌐 hufflabs.dev · 📫 james@hufflabs.dev

HuffLabs, my homelab

A self-hosted environment I designed, secured and run day to day.

Area What I run
Virtualization Proxmox VE with LXC containers and VMs, Docker
Storage and backups TrueNAS SCALE with ZFS, scheduled guest backups, encrypted restic backups
Networking Self-hosted DNS with filtering, reverse proxy with TLS, Tailscale, Cloudflare Tunnels
Identity and security Authentik single sign-on, role-based firewall rules, fail2ban, recurring security audits
Monitoring Checkmk, plus a Python watchdog I built that sends alerts and takes commands in Discord
AI agents An on-call agent for critical alerts: known problems get an allowlisted fix, and anything else goes to AI triage, limited by a gatekeeper that logs every command and rate-limits fixes
Automation Python, Bash, Lua, Go, systemd
Operations Runbooks, incident write-ups and disaster recovery documentation

Almost all of it runs on one GMKtec M6 Ultra mini PC (Ryzen 5 7640HS, 64 GB DDR5) in a 22U rack. Nothing on my home network is open to the internet: public sites come in through Cloudflare Tunnels, and I reach everything else over Tailscale.

Diagram of the 22U rack: the Cisco 2960-X going live next, open space, the mini PC, a planned second server and UPS, and the storage shelf

Diagram of the mini PC: traffic enters through Cloudflare Tunnels or Tailscale, and inside Proxmox are network, storage, app and monitoring services

Proxmox guest list: ten containers and two VMs, each tagged by role

Checkmk dashboard with graphs for the host, key services and the router

Technitium DNS dashboard: about a quarter of lookups blocked in one hour

What's next: bring the Cisco 2960-X online (its VLANs are already set up, so the work laptop and smart-home devices each get their own network), add a rack UPS, move the M6 to 2.5 GbE, and add a Dell R730 as a second node.
