I'm a software engineer based in the San Francisco Bay Area. I work at Stripe helping businesses issue credit cards. I recently created Select Star SQL, an interactive book for learning SQL and Socratic Regression, a geometric guide to linear regression.

Some of my formative experiences were at:

  • The Chinese High School, Singapore
  • Delta Wing, Officer Cadet School
  • The University of Chicago
  • Quora's data science team
  • The Recurse Center

The outdoors are a big part of my life. I climb and sail.


In math, a morphism is a transformation that preserves the structure of a space. Likewise, a kaomorphism applies Kao's worldview while, at least in theory, preserving the fundamental truths of the world. A kaomorphism could also refer to the Kao - Eric Morphis friendship.
