Jeff, was not only able to solve the underlying problem but went over the solution step by step. The session was invaluable in my learning experience with angularjs and understanding Nodejs a bit better. Thank you, Jeff!!

Built a multi camera streaming platform for the Poker industry for streaming numerous cameras from a live card table to each of the player’s that are part of the game. Each player is also able to see each other by the system streaming their web cameras to each other. The system was built using Golang for the backend streaming services, Angular for the frontend application, and a variety of custom Raspberry Pi devices for streaming the video of the dealer, card cameras and card scanner to the cloud. A messaging platform for event propagation was built using Kafka with AWS’s MSK service. The overall platform was deployed using AWS’s EKS (Kubernetes) service.
