Open Source Projects
A powerful multitool for exploring data in the terminal. Easily wrangle gigabyte datasets from many different formats. Written in Python3 with very few dependencies and an extensible architecture.
70,000 crossword puzzles parsed and cleaned into a simple text format. The grid comparison analysis uncovered rampant self-plagiarism by a major crossword editor. The minimalist data pipeline is written in Python3 and deployed on AWS.
Bootable ISOs of classic games using custom unikernels. Minimal size, rapid bootup, curated experiences.
Recurse Center, New York (Spring 2017)
A 12-week self-study program in NYC. Studied open source development practices, participated in a game jam, and led workshops on kernel development and implementing Forth.
