Hi, I'm Andrew. I'm Co-founder & CEO of Glass Devtools (YC S24). If you're reading this, feel free to send me an email!

Cornell '21 - BS in Computer Science, minors in Physics and Math. I decided to take a lot of non-required physics classes instead of graduating early.

Startup

  • Void

    Built Void, an open source AI coding tool that grew to 28k stars and over 200k users. I led most of the development and managed our community of 45+ contributors.

  • GlassJS

    Built GlassJS, one of the first vibe-coding tools, predating Lovable and Bolt.

  • DeriveIt

    Built DeriveIt, a CS fundamentals course. It's used at Cornell and by students all over, and I highly recommend it - it completely changed the way I think about algorithms.

Things I made pre-GPT

  • Reelers.io multiplayer game
    reelers.io is a multiplayer io game I built from scratch on an HTML canvas & WebSockets.
  • Crystal energy band visualization
    Crystals-And-Dislocations lets you visualize wavefunctions and their energy bands near defects.
  • A photo of a cube from 3DTest
    3D renderer is a graphics project I derived the math for and built in Java.
  • custom-markdown is a markdown parser I wrote from scratch that compiles custom grammars to React. Used in DeriveIt.

Projects post-GPT

  • Kube.new
    Kube.new is a game platform (+ engine!) made from scratch in Rust, 150k+ LoC.
  • BranchTracker
    BranchTracker is a desktop app I made to keep track of all my unmerged worktrees when using Codex and Claude.
  • scope-tailwind lets you drop Tailwind into an existing CSS project without style conflicts. Used in Void.
  • unfunction
    Unfunction lets you unravel TS by clicking functions. Weekend project that I always wanted pre-AI.
