Colloquium - Video Conferencing Platform

Colloquium is a state-of-the-art conferencing platform tailored for large-scale meetings and seamless collaboration. It supports live video, audio, screen sharing, external media sharing, chat, reactions, and advanced moderation tools. The platform was engineered with a focus on scalability, low-latency communication, and data efficiency, making it suitable for both small teams and large organizational events.

I led the end-to-end design and engineering of Colloquium, architecting its WebRTC infrastructure and building features like video/audio streaming, screen sharing, chat, reactions, and recording. I optimized both frontend and backend systems to deliver a secure, scalable, and low-latency conferencing experience for up to 1,000 participants.
