Live Video Streaming Shopping Application

A React app supporting live video streaming combined with eCommerce. The host app allowed a host to broadcast on the platform and add an additional expert to the video call. The consumer side allowed one to watch the stream and purchase the demonstrated products. The host app was React Native, and the consumer side was React video streaming using Agora.
