My name is Theodore Chu. I also go by Theo, Ted, and Teddy, but I always introduce myself as Theodore. I am a United States citizen by birth.

I'm a philosopher, mathematician, and technologist in the San Francisco Bay Area. I enjoy creating free and open-source productivity tools and writing documentation for open-source projects.


I currently work as a technical writer at Roblox to help creators of all skill levels achieve their visions. In the meantime, I'm trying to do my part to ensure that our technology, government policies, and institutional practices respect and protect our rights, freedoms, and liberties.


My formal training was focused on philosophy, mathematics, and science. I finished my undergraduate education with a double major in Mathematics and Philosophy in May 2021. My independent studies are focused on computer science, art, and technology. I'm interested in game design and development, web development, application security, cryptography, and blockchain technologies.

I like to read. Some of the books that I've read are listed on my personal docs site.


In May 2021, I joined Roblox as a full-time Technical Writer. My responsibilities include:

  • Learning and using products and features such as Roblox Studio and Lua and REST APIs.
  • Write technical documentation such as API reference docs, conceptual and task-based feature guides, and tutorials.
  • Help drive better information architecture and developer experiences with cross functional teams such as Developer Relations, Engineering, Product, and Design.

I previously worked at Standard Notes, a free, open-source, and end-to-end encrypted notes app available on Mac, Windows, iOS, Android, Web, and Linux. Learn more in my post, "Working at Standard Notes".
