Tristan has been programming since he got his first computer at the age of 10. He earned his Bachelor's and Master's degrees in Computer Science from the University of Chicago. After graduating, he went to work at YouTube/Google, on the HTML5 video player, improving live streaming latency from 15 seconds to 2 seconds and enabling new uses cases like a gapless transition for ad videos.

HTML5 Video Player

I contributed to an HTML5 video player, with my primary focus being on live and encrypted playback.

The player was written in JavaScript, but I worked closely with the server teams, primarily in Python.
