I'm Curtis Fenner. I graduated from the University of Michigan in 2018.

I enjoy working with code and math!

A simple automatic proof-verifier for students learning proofs in JavaScript and Perl. The checker manipulates symbolic representations of mathematical statements and verifies the steps taken in a formal proof.
