Hi, I'm Geoff
I love to teach, and I love to code.
I teach students to code.

My goal is to teach computer science to as many people as possible. I do this by creating interactive learning environments that scale. You can explore an example of my materials at learncs.online.
Here's a long bio, or perhaps you'd prefer something shorter.
Essays
