I am a contributor to the Homebrew-Core open-source project, a collection of package configuration files written in Ruby for Homebrew, the MacOS package manager. My main contribution thus far has been fixing system calls for 25 different packages to make them more robust.
I redesigned (and am currently improving) the Swarthmore College Computer Society homepage using Jekyll.
Also check out Bubbles, a fun but completely useless interactive toy using p5.js.
See my GitHub for in-progress projects and source code.
