My projects are hosted on GitHub. For a VCS, I started with git (using GitHub Desktop 💩). I transitioned to interacting with git solely through the command line. I won't pretend I know how to use git like crazy. I've since been introduced to (and really enjoy) jujutsu (hereafter referred to as "jj").
Blackjack
I tried my best to recreate the game of blackjack. While I originally took a crack at it in Java, I am actively working on a Python implementation.
