imjasonh/README.md

Hi, I'm Jason H 👋

(he/him)

I work at Chainguard, securing software supply chains by default

Before that I was at Red Hat, and before that Google Cloud, where I cofounded Google Cloud Build and Tekton.

You can also find me on Twitter.

I contribute to ko and go-containerregistry, and a number of other things.

I build fun toys like https://kontain.me and https://gcping.com.

Resume

My resume is a CRD you can install on your Kubernetes cluster:

kubectl apply -f https://raw.githubusercontent.com/ImJasonH/ImJasonH/main/resume-crd.yaml

(You wouldn't install something off the internet without reading it first, would you?!)

Talks, etc.
