Languages
Go
Go appeales to me because of its slim syntax and idiomatic approches to problem solving and has become my
language of choice for productivity on the backend and wherever a problem is complex enough that the language
to solve it should be simple and out of the way, especially when working on Code interacting with Kubernetes.
JavaScript
I have been involved with JavaScript since the early days of Node.js. As a developing technology with new libraries
and tools being released on a daily basis, JS proved to be a great platform for experimenting with exciting
new technology and nearly universal portability.
Though I'm no longer writing JavaScript on a daily basis or try out every new framework, I'm still quite proficient with it.
