Queue.gg is a platform that allows people to collaberate on multimedia content in real time. It helps gamers talk with their friends and teammates to identify weaknesses or ways they could play better. Professionals who work with video can use Queue for instant feedback instead of mailing around GBs of video files.
I personally built both the recording software for Queue and parts of the video player. The recorder allows high performence, high fidelity video capture so that gamers can record their gameplay without having to worry about frame drops and lag. I also contributed to the syncronized video player that lets multiple users watch and collaberate on a single video.
