Vitals 2026

A real-time map of NYC: subways, buses, ferries, tides, weather, the power grid, and 311 complaints streaming onto one MapLibre + deck.gl canvas over WebSockets. It never looks the same twice, because it reflects the actual city, right now.

NYC Rat Index 2026

Type a NYC address, get a Rattiness Score from 0 to 100, ranked against every ZIP code in the city. A daily ETL pulls 311 rat-sighting data, computes percentile rankings, and generates shareable OG images per neighborhood.

Over/Under 2026

A fast, mobile-first higher-or-lower game: one card shows its value, the other hides it; guess right and chain a streak. Four categories, from fast-food calories to country populations, in pure HTML/CSS/JS served from a Cloudflare Worker.

xcode-remote 2026

A small Python CLI that closes the build-run-observe loop for AI coding agents. One command builds on the build host, launches the app on the machine you're watching (macOS, simulator, or a real iPhone), and hands back build errors, logs, and crash reports as a single JSON object.
