## Projects

### [Double Down Trivia](https://doubledowntrivia.web.app)

Real-time multiplayer trivia where every answer is a wager. *Next.js, React 19, TypeScript, Firebase*

- Used React 19's useOptimistic and startTransition for instant UI feedback, with a game loop built on Context and custom hooks that keeps multi-phase state in sync across concurrent clients.
- Built the real-time backend on Cloud Functions and Firestore, using atomic transactions to keep scores consistent and eliminate race conditions during simultaneous scoring.
- Wrote a typo-tolerant answer matcher using Levenshtein distance, plus error handling with exponential backoff so sessions survive unreliable networks.

### [Snail Mail](https://snailmail-post.vercel.app)

Letters that travel at the speed of their carrier, from an hour by pigeon to a year by snail, tracked on a live map. *Next.js, Vercel Workflow, Postgres, Drizzle, AI SDK*

- Modeled each letter as a durable Vercel Workflow run that sleeps until arrival, then delivers and notifies, with a daily cron sweep as a safety net.
- Rendered routes on the server with d3-geo and Natural Earth data, served as cacheable SVG layers themed with CSS masks.
- Built handwritten letters two ways: photo uploads of real pages, or an image model (via AI Gateway) tracing typed text onto chosen stationery.
- Hardened it for strangers with BotID, Postgres-backed rate limits, blocking, reporting and an 18+ pen-pal directory, in five languages.

### [MoDate](https://modate.org)

Free volunteer matchmaking for the Modern Orthodox community, with a workspace and iPhone app for the matchmakers. *React 19, Vite, Firebase, SwiftUI*

- Built a scoring engine for candidate pairs (age range, religious level, Kohen rules, location, aliyah plans) with admin-tunable rules, ported to Swift so web and iOS rank identically.
- Shipped MOSwipe, a swipe and ranked-list interface for proposing matches, on the web and in a native SwiftUI app.
- Used Firestore live listeners with a multi-tab offline cache, transactional claims and handoffs, and push, email and WhatsApp reminders for volunteers.
- Added AI screening of new signups and AI match analysis through xAI's batch API.
