I’m a (ex-) Google trained SRE. Familiar with operating and building large and distributed applications (Borg in Google, Kubernetes in (GKE) and outside Google). This includes traffic management, observability and automation. As a long time Linux (Debian) user (kernel version 1.2, March 1995) I’m fluent in shell, system management and various computer languages. Most of my current projects are written in Go. I have expert knowledge of the Domain Name System and created various software projects and Internet RFCs: RFC 7328, RFC 7129 and RFC 6781.
