I’m a 2L at Brooklyn Law. Outside class, I build small tools for legal research, public data, and travel.

That work has taken me from citizenship statutes and consular paperwork to military flight schedules, GPS data, and a baseball model with a public track record.

2Pass

Research prototype · 2026

The paperwork came first.

Getting Israeli and Czech citizenship meant months of statutes, consular guidance, translation questions, and apostilled documents. 2Pass grows out of that work: a research prototype for organizing eligibility questions, sources, and document order.

Space-A

Web + iPhone · 2026

The schedules were everywhere.

Space-A schedules are fragmented across terminal pages, 72-hour posts, PDFs, and social channels. I built the schedule ingestion, terminal search, watches, alerts, trip planning, web app, and iPhone app around those sources.

Revv

iPhone · 2026

A drive tracker should work for the driver.

Revv records drives, keeps garage history, supports privacy zones, and turns finished routes into shareable cards. I built the React Native app, GPS upload pipeline, Mapbox routes, AutoDrive flow, and App Store release.

Right now

Heading into 2L at Brooklyn Law. Reading the Rottmann line for 2Pass, keeping Space-A running, improving AutoDrive reliability in Revv, and working through Patrick Collison’s reading list.
