Many! I worked with the Experience Design team for more than ten years. I was part of the original launch of Xfinity X1, developed the voice and experience around the Xfinity xFi app and Xfiinty Home. Projects varied week to week and month to month, as I partnered with a variety of internal teams on a host of deliverables.
A few samples from Xfinity X1, here a basic intro to services as seen on a "For You" promo screen.
