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 7719, RFC 6781.
The following projects are created by me:
- An advanced DNS package.
- CoreDNS a flexible and fast DNS server written in Go.
- A PKCS11 interface for Go.
- ldns a C library to easily interface with the DNS.
See my GitHub page for various other packages, half backed ideas.
