I work at 
Chainguard on infrastructure to build and deliver Chainguard Images.
Before that I was at 
Red Hat, and before that 
Google Cloud, where I cofounded 
Google Cloud Build and 
Tekton.
I contribute to ko and go-containerregistry, Wolfi, Apko, Melange, and a number of other things.
I sometimes build fun toys like:
- a Chrome extension to let you quickly switch to the tab making sound
- a container image registry that generates images on-demand
- a page to show you how far away you are from every GCP datacenter
- a plugin to manage GitHub PRs in Google Sheets
- a Google Meet plugin that shows how many hours of human time this meeting has cost
- a script for generating presentations with automated voiceover
- a multiplayer chess game in your terminal, over SSH
- a multiplayer old school FPS in your terminal, over SSH
- a Git repo that always has changes to pull
- an experiment to use Go as a scripting language
- a novel way to browse Git history
Sometimes I make lil GitHub actions to do useful things:
