Systems builder · Colorado Springs

Hi, I'm Gareth

I build the part that makes the other parts work — software, infrastructure, connected hardware, facilities support, field installation, and practical automation.

About

Experience that crosses lines.

My background spans telecommunications, facilities, deployment, troubleshooting, service restoration, and technical operations. I like projects that refuse to stay inside one box.

Recent work combines web and mobile applications, Linux servers, Node.js services, connected electronics, LoRa telemetry, and fabrication. I think in systems — not just screens.
