Nate Levy's Portfolio
My internship, the projects I've built, and my research.
Sonar Guard
Sep 2026
An ultrasonic turret that learns what a room normally looks like, then sweeps it and flags anything new.
You can run the dashboard in your browser with a simulated room and intruder.
Scanning Rover
Apr 2026
An Arduino rover that checks three directions with an ultrasonic sensor and drives toward the most open one.
It turns in smooth arcs, with the two wheels at different speeds, so the back corner clears what it just turned away from.
Cadence
Aug 2026
A macOS dictation app that sends what you say to whichever app you name.
It's signed and notarized by Apple, and you can download the installer.
Desky
Sep 2026
A voice-capture web app that files my spoken notes into my calendar or task list.
Captures are saved on the phone first and retried until the server confirms them, so nothing gets lost or doubled.
Found It!
A macOS search tool that finds files by what's in them instead of their filename.
Everything runs on the Mac, and files never leave it.
Notetaker Clasp
In progress
A voice-note recorder built into the clasp of a 10 mm Cuban link bracelet. It's designed in CAD but not built yet.
Every part fits inside a 20 x 10 x 4 mm titanium clasp, checked for collisions in SolidWorks.
Whale Signals
Jun 2026
An event study testing whether large Polymarket bets predict moves in related stocks.
604 markets, 2,623 signals and 16,731 observations, written up as a full paper.
Cross-Venue Spreads
Jul 2026
A study of price gaps between Kalshi and Polymarket on the same events, measured after fees.
74 of 223 price gaps stayed profitable after fees, in a paper simulation.
