TL;DR — Virtual Events Platform

Design a virtual events platform similar to Hopin or Zoom Events that supports conferences with up to 50K attendees. The platform must handle multiple content modalities: a main stage with live speaker video streamed to all attendees, breakout rooms for interactive sessions (up to 50 participants each with video/audio), a networking area where attendees are randomly paired for 1-on-1 video meetings, and an expo hall with sponsor booths. All of this must be backed by a ticketing and registration system. Key features: Main stage: live video from speaker panel streamed to 50K attendees. Breakout rooms: interactive video sessions with up to 50 participants.
