About
Hey! I am Joey. Currently a student at McGill University studying Computer Science.
There are a couple of things I am quite interested in:
- Database Systems
- Compilers - I have built a mini C compiler before
- Functional Programming
- Observability
- Text Editor - Neovim
- Personal Finance - I am building beavermoney.app
- Food
I currently work at the Rates Technology team at Citadel Securities.
In the past, I worked as a founding engineer at a startup called Flojoy. With my team, we raised 1.3M USD to bring modern test, measurement and control (TMC) tooling to heavy industries where software hasn't kept up. Besides this, I've worked at companies such as Meta, Wealthsimple, etc.
If you have similar interests, or just want to say hi and chat, feel free to hit me up :)
I recently started documenting my learnings at til.jyu.dev, go check it out!
