Aluf HaTorah
A family trivia game on the weekly Torah portion, with levels, streaks, leaderboards and challenges between friends.
- Android
- Web
The challenge
The goal: a game the whole family plays together before Shabbat. Questions on the weekly portion at different difficulty levels, with a sense of progress that brings you back every day, plus a full English version.
Behind the simple game is a complete system: one app that runs on Android, iOS and the browser, a backend that computes scores and leaderboards fairly, scheduled push notifications, deep links for challenges, and an AI-assisted content pipeline that produces questions and sourced learning notes in two languages.

Hard problems I solved
01 One codebase, three platforms
- Approach
- Expo and React Native with react-native-web. EAS builds with automatic version numbering, and a static export of the web version to Vercel.
- Result
- Every feature ships to Android and web together, and the iOS build is ready from the same code.
02 A fair game backend
- Approach
- Scores, XP, streaks and leaderboards are computed server-side in Supabase RPCs, with 25 migrations managing the schema.
- Result
- The leaderboard can't be gamed from the client, and the schema evolves without breaking existing players.
03 Bringing players back every day
- Approach
- Edge functions send daily reminders, achievement alerts and new-content notifications. Deep links power invites and friend challenges.
- Result
- A daily habit and natural sharing between family and friends.
