Staff Software Engineer — systems, Go, Zig & locally-run AI
I've spent the last 15 years building systems software: observability shipped to millions of hosts at Datadog, industrial cybersecurity at Sentryo, high-volume backends at Batch and AppGratis. These days I'm a staff engineer at Hackuity, and at home, a homelab inference infrastructure hum in my basement so I can run models locally. I write here about what I build and what breaks.
