Hello, I'm Jeffrey Thi.

Languages I've used

Click an icon for a quick note on where I picked it up and what I built with it.

Python

  • I have used Python for most of my personal projects.
  • Something that stood out to me was the amount of, in a sense, non-programming work you have to do to push code to production.
  • One project I enjoyed was using Python to test out a type of machine learning algorithm called NEAT.
  • A project I'm very proud of is my Discord music bot.
  • My friends used to bond over playing music for each other, so coding this was amazing.
