the problem
Live classroom quizzes require perfectly synchronized state across dozens of devices on spotty school Wi-Fi. The requirement was a fully functional iOS app that felt tactile and playful, without dropping connections during critical game moments.
the approach
Engineered a production-ready iOS application featuring 54 distinct screens and 14 complete flows. Built robust live lobbies to support up to 1,000 concurrent players per game, handling complex real-time interactions like spatial drop-pins, interactive polling, and live leaderboards.
