Web Platform
Live classes, recordings, assessments and payments for 45,000 students — rebuilt to survive its own launch traffic.
Their first version, assembled from off-the-shelf tools, collapsed whenever more than 300 students joined a live class. Video, payments and assessments were three disconnected systems, and student progress could not be tracked across them.
A single Next.js platform with WebRTC live classes backed by an SFU, automatic recording, in-platform assessments and integrated payments. Load-tested to 5,000 concurrent participants before launch rather than after.
The platform handled a 4,200-student launch class without incident. Course completion improved once progress tracking made stalled students visible to instructors.
We will walk you through how we would approach it — scope, risks, timeline and cost.
