About Me

Dubbed by some as "Hank Green's cousin" and by others as a "wonk"1, I'm currently an iOS engineer at willowtree, having built apps for Empathable, Fox Sports, Telus, and ███████, a Fortune-50 carrier.

I had a few stints as intern:

  • Whoop (iOS widget, Smart Alarm, + other sleep features)
  • Tomorrow Ideas (localizing the backend API in PHP ✨).
  • AIHealth, a research project to track spinal health

And while this wasn't an internship per-se, leading the group at BrickHack was an invaluable time:

  • Built the BrickHack 6 iOS App (GitHub)
  • Maintained HackEngine, our Rails event-management tool
  • Led development on the BrickHack 7 website, and authbot, a Discord bot for auth
  • Ran the team of ~6 hard-working, hilarious people thru covid, hell, and back

This was preceeded by three years RIT (CS), after two years at UW (CS+music).


Other interests include open-source (swift-package-manager, Zola, Firefox-ios, etc.), evangelizing Setapp/Sublime Text, and fussing over code quality.

Other other interests include improvising piano, performing piano (currently Pathetique sonata, French Suite No. 2, Impromptu No. 2 in Eb Major), singing (choir, baritone), and making elektronik beatz. I'm a person too, though! Promise. I like cats and memes and stuff. Pepperoni and sausage pizza. Vanilla sweet cream cold brew. The Mistborn trilogy. John Green! Discord! The color purple! ミ★ 𝘰𝘷𝘦𝘳𝘤𝘰𝘮𝘪𝘯𝘨 𝘵𝘩𝘦 𝘤𝘦𝘢𝘴𝘦𝘭𝘦𝘴𝘴 𝘢𝘱𝘱𝘳𝘰𝘢𝘤𝘩 𝘰𝘧 𝘥𝘳𝘦𝘢𝘥! ★彡
