EdTech Exam Preparation Platform 50,000+ Concurrent Users
Built a scalable exam preparation platform handling 50,000+ concurrent users with real-time quiz engines, progress tracking, and AI-powered analytics.
The Challenge
The client needed to launch an exam preparation platform for government job aspirants within 5 months, supporting multiple exam categories, real-time test-taking, and analytics — all while handling massive traffic spikes on exam announcement days.
Our Solution
We built a Progressive Web App using Angular with SSR for SEO, a Node.js/Express API with MongoDB for flexible quiz data structures, Redis for session management and leaderboards, and WebSocket connections for real-time test synchronization. The platform was deployed on a VPS with PM2 and Nginx.
