I joined Slack in early 2015 as the lead product designer for their iOS platform. My role was to ensure that iOS designs we're keeping pace with the desktop teams, and their goals.
I partnered very closely with the iOS engineering team. Helping to get dozens of features and improvements shipped ontime and of a high quality.
I also helped to design systems to be reused throughout the product. Including typographic systems throughout the app. As well as displaying file types and images and designing the experience around consuming that content on iOS.
I also worked on the creation of Reactions, or as they're sometimes called Reacjis. A solution that allowed for members of a team to quickly respond to a message. Whether that to say, yes I'm working on it, or to show joy when something great happens within a team. It was a means to go beyond just a like button.
