Lattice
A task runner and toolchain manager for monorepos in any language. It figures out what each workspace already uses, runs everything in dependency order, and caches the results so you only build what changed.
Work
Some are for clients, some I built because I like it.
ArenaSwap
A browser extension that watches every live game in your tabs and swaps you to whichever one is most exciting in the moment, scored by a custom algorithm I built called PowerScore.

Coursework + personal projects from Northeastern.
The Book Nook Project
