1. Recruiter-Friendly Summary
In competitive quizzes, resolving who clicked a buzzer first must be completely fair and immune to local rendering delays. Traditional polling architectures are too slow.
2. Platform Features & Architecture
Developed a real-time WebSocket dashboard using Socket.IO. When a player buzzes, the server locks out other contenders and broadcasts the locked state immediately, preventing disputes.
3. Engineering Challenges
React and Tailwind CSS frontend built with Vite. Backend uses an Express server with Socket.IO listeners processing incoming websocket events against server-side question databases.
4. Implemented Solutions
Delivered a zero-delay mobile-first buzzer interface that handles high-concurrency buzz storms gracefully.
