Proxmox cluster
A Proxmox VE cluster of LXC containers and VMs, one service each. A heartbeat monitor alerts me when a node drops, and guests get a snapshot before every change.

By day I install and repair fiber for AT&T. After hours I run my own infrastructure: a Proxmox cluster, a GPU box that answers questions, and a few game worlds for friends. This page is served from that same hardware.

// WHO I AM
Fiber by day, Linux by night.
I am a field technician in North Dallas with 3+ years installing, testing and repairing fiber, copper and premises network hardware. My days are trouble tickets: find the fault, restore service, get it right on the first visit.
At home I like knowing how the whole thing works, from the cable in the wall to the certificate in the browser. So most of what I use runs on machines I own, each service in its own container, with a snapshot before anything risky and a note about what I changed. I work in English and Spanish.

// WHAT I RUN
› ai
Local LLM box
A dedicated GPU machine serving a quantized Qwen model over an OpenAI-compatible API. My agents and scripts use it instead of a cloud provider.

› networking
Network edge
A UniFi network segmented into two VLANs, Pi-hole for DNS, and a WireGuard tunnel to a Debian VPS so the public pieces never need an open port at home.

Internal PKI
My own root certificate authority. Caddy requests certificates from it automatically, so internal services get real TLS with no browser warnings.

Game servers
Three modded Minecraft worlds for friends, each in its own container. Every mod change starts with a snapshot, so a bad update is a two-minute rollback.

This site: one hand-written HTML file with no framework and no tracking, on a 256 MB container in the cluster above.
