Embedded systems (specifically, OS development) and Machine Learning are currently my thing.
I mostly do backend languages (specifically, C++, C, NASM assembly, and occasionally Python, Java and PHP), however I sometimes dip my toes into the world of frontend (mostly JS with JQuery).
For obvious reasons I generally prefer lower level languages. Speed is very important to me. As your average up-themself developer, I use Vim and hate on Python devs (all in good fun, no harm meant!)
