Felix, the “DevOps” between designers and developers

— Building Felix, the Design System for Groupon Several new features have been released on Groupon.com recently, such as the QR code in the navigation bar to download the app, and a banner carousel to display multiple banner messages within a single view. In the past, similar product features might take 2–3 sprints to complete, but now all of these features are developed and tested in a single sprint. The reason why we can finish the development and testing efficiently is mainly credited to Felix, the design system we’re building for Groupon.
