I run frequent company-wide webinars and need a dependable livestreaming environment that can handle several sessions at once. The must-haves are smooth screen sharing and a real-time chat panel; recording is optional but not critical for this phase. During peak events we split our audience into parallel tracks, so the infrastructure has to manage multiple simultaneous streams without degrading quality. I’m open to whatever stack you’re most comfortable with—Zoom, Teams, Jitsi, a custom WebRTC build on Agora or Twilio—provided the final result is rock-solid, secure, and easy for my team to run after you hand it over. Brandable landing pages and basic analytics would be nice bonuses, though stability comes first. Deliverables • Fully configured platform that supports at least two concurrent streams, each with screen sharing and chat enabled. • Clear, step-by-step admin guide so my staff can launch future webinars unassisted. • One live rehearsal and a brief support window to resolve any post-launch issues. Acceptance criteria: a 30-minute test with no dropped connections, screen-sharing latency under two seconds, and instant chat delivery across all active streams.
