I build software around Identity and SSO, and also other things sometimes.
I mainly work on authentik, an IDP focused on being easy to use and flexible, and also make a couple tools to test Identity protocols:
Also for some reason I decided to make my own DHCP and DNS Server, Gravity.
I also like to use a lot of IaC workflows for my lab, like infrastructure with Ansible/Puppet/Terraform and k8s with Flux.
