The team and product I worked on at Google are still unreleased so I can't disclose much as I'm a little tied down by the legal stuff. I can tell you a bit about what I did there though?
I was tasked to design for Android, web and mobile web. Even though my title was an Interaction Designer, I heavily contributed both on the interaction and visual end. We designed using the Material Design guidelines to stay synonomous with other Google products. User studies, illustrations, wireframes and animated prototypes were all part of the gig. I contributed to the Material Design language as well so you may have already come across some things I've built.
