I'm transitioning to using Elixir full time. I try to use it as much as I can on my free time as well. I'm excited to mentor folks starting out and can hopefully learn new things as well!

Python is the first language I taught myself, and the one I used at my first job. I love its relative accessibility to newcomers and the huge ecosystem you can grow into as you learn it!

Ruby was the starting point for me learning to program. It still is my go-to-language for web applications and my knowledge made it easier for me to learn new languages I use at work.

I mostly write Ruby on Rails professionally but for fun (and possibly profit one day) I dabble with Elixir, Nim, Arduino, and such. I’m really digging both Nim and Vim lately.

I love python for its readability and general-purpose. There is an open source library for basically everything. If you can imagine it, it probably exists. That's fascinating.
