EverFi builds digital courses for students, and Deck Builder is a game pattern designed to let 9th through 12th graders make choices in a safe environment and see how those decisions play out — specifically across courses dealing with emotional intelligence. When the course design team was tasked with implementing it into live courses, it wasn't ready. Confusing interactions, poor visual hierarchy, and unclear data visuals needed to be resolved before it could ship. Working within the constraints of a pre-built backend, the team refined the experience and introduced Lottie animations tied directly to user selections — giving emotional weight to every choice. Beyond fixing the game, I systemized the approach into a reusable framework that was subsequently used across multiple EverFi courses.
