I am a Software Engineer usually working as DevOps or Back-End developer. I feel comfortable using various Linux distributions (usually at work I have Debian\Ubuntu\Red Hat\CentOS and even {Open,}SuSE. Whenever I can, I use Gentoo and NetBSD).
My tools of choice are Python, Go and C.
I wrote a little book about Kubernetes Operators in Python and Go! Take a look at my CLI framework for Python.
