Challenges
Before

The client needed an online lesson platform built from scratch — covering instant interactive live streaming, end-to-end booking-to-payment, and instructor monetization. Cobbling together off-the-shelf tools created latency, drop-offs, and operational overhead that blocked business growth.

  • Deliver live lessons with low latency and bidirectional interaction
    Off-the-shelf tools: one-way or seconds of latency
  • Complete booking, payment, and attendance in a single flow
    Multiple external tools causing drop-off before enrollment
  • Automate revenue distribution to instructors
    Manual tallying breaks down at thousands of users
  • Deliver recorded catch-up content securely
    No support for post-stream replay demand
Solution
After
