I've run a multi-million dollar restaurant end to end for eight years, and I built its web and ordering infrastructure, its network and its accounts myself, because there was nobody else to do it. Somewhere along the way the technology stopped being the chore and became the job I wanted.

These repos are my infrastructure, written up the way I'd explain a design to someone deciding whether to trust it: the problem, the design, the trade-offs, and what changes at scale.

• ai-agent-engineering: how I directed AI coding agents to take a multiplayer game from an empty repo to working playtests in twelve days, with the method, the measured results and the failures
• nextcloud-cloudflare-tunnel: a self-hosted platform publicly reachable with zero open inbound ports, threat model included
• restaurant-web-infrastructure: the production stack that runs a real business, with the incident runbook and tested backups
• vlan-segmented-network-security: a six-VLAN network with default-deny firewall policy and DNS as a security control

Also running at home: a four-node Proxmox cluster, monitoring that pages me, offsite backups, and a self-hosted AI assistant with retrieval over my own docs. I build most of the automation around it with AI coding tools, and I check their work against the live system before I trust it.

Find me on LinkedIn, or see the demo site at brockharries.dev, served from my own rack through the zero inbound ports design in the Nextcloud repo.
