Glenn Walker Infrastructure · SRE · AI Platform

12 years of infrastructure. Now leaning into inference.

Networks, identity, fleet, facilities — all built under real constraints with real users. Now applying that operational depth to GPU inference: serving, routing, observability, and the physical layer underneath.

Currently

What I’m building right now.

  • Running a LiteLLM model router at an edge node, routing inference to GPU workers in the lab over WireGuard. The platform changes constantly — that’s the point.
  • Exploring passive RF observation with a Pluto+ SDR and Nordic BLE sensors. Interested in what ML can do with raw signal data — especially at the link layer.
  • Most of my non-work time is in the lab. It’s where I stay current.

Essentials

Things that make the long hours better.

  • Large format screen. Once you go big, everything else feels like squinting.
  • Clickiest mechanical keyboard I can find. Always.
  • Old Steelcase chair. Not a Herman Miller person.
