Overview
Quiz Room Application built for classroom-style assessments. Instructors can create and manage rooms, upload test modules, and track leaderboards; students join active rooms, attempt quizzes, and view rankings. Backend services run on Node.js/Express with Prisma ORM over MongoDB, JWT authentication, bcrypt hashing, multer-s3 uploads, and node-cron for scheduled tasks. Infrastructure uses AWS (EC2, ALB, S3, Route 53, ACM), while the frontend is hosted on Vercel.
Highlights
- Room lifecycle management with activation scheduling and leaderboard access.
- Test module uploads to AWS S3 via multer-s3.
- Prisma schema for quizzes, users, rooms, and results in MongoDB.
- JWT authentication with bcrypt password hashing.
- Scheduled jobs via node-cron for maintenance and updates.
- AWS infrastructure with SSL and domain routing plus Vercel frontend hosting.
