I am a happiness miser and senior developer.
Professionally, I use F#, C# and Python, and work on automated build systems, automated and distributed infrastructure, and navigating company politics.
Outside of work, I mainly use Clojure and Python. I am also what most would probably consider expert-level in C++, C#, and Java. My C, however, has become extremely rusty in the past 10 years from disuse.
I am also part of mochify, a collective of developers looking to make better software for all.
As a note: I give terrible programming advice, so I hope you read this before you read my answers!
If you want to follow my weird irreverent sense of humor, you can try to make sense of my twitter stream: @birryree
