Solo build
Buying a recorded course gets you the video classes, and access to the tutor who made them. A personalised experience.
A learning platform where students browse and buy courses, then actually talk to the tutor who wrote them. Text chat over Socket.IO and scheduled one-to-one video calls over WebRTC. Tutors get a dashboard for course management, earnings, and student progress, with an admin role above both.
What it does
Three roles, each with its own view of the same system.
Students browse the catalogue, buy a course through Razorpay, and work through it with progress tracked as they go. They can message the tutor directly and book a one-to-one video session.
Tutors publish and update courses, run their own dashboard for earnings and per-course performance, schedule video sessions, and follow how their students are progressing.
Admins sit above both with a dashboard covering the whole platform.
How it’s built
Next.js on the front, Express and MongoDB behind it, deployed to EC2 with media in S3. Auth is JWT with access and refresh tokens. Chat runs over Socket.IO; video calls are peer-to-peer over WebRTC with the socket connection handling signalling.
Why I built it end to end
I wanted one project that contained all the parts I hadn’t done yet: real-time messaging, peer-to-peer video, payments, role-based access, and a dashboard that had to aggregate real numbers. Building them separately would have been easier and would have taught me less about how they interfere with each other.
