Project Overview
Lessoons is a comprehensive interactive e-learning platform delivering low-latency live video streaming, synchronized interactive whiteboards, course subscription billing, and automated instructor payout scheduling.
The Architectural Challenge
Streaming interactive video lectures to hundreds of concurrent global students required adaptive bitrate video encoding, real-time WebSocket messaging, and PCI-compliant recurring billing across diverse local currencies and tax jurisdictions.
