Christopher Sim
Software designer based in San Francisco
Currently, I'm a designer at OpenAI working on Codex. Previously, I was one of the earliest designers at Harvey, where I worked on the frontier AI platform for legal, my work has touched almost every surface of the product and laid the foundations for where Harvey is today.
I've also had stints at Flexport, Uber, and Arc. In my free time, I'm a design advisor for emerging software companies backed by top VCs.
I love working on niche problems and simplifying complexities so people can focus on more valuable work. I received my masters in Human-Computer Interaction from the University of Washington. You can reach me at @thisiscsim or hello(at)csim.me.
