Forked the Google IO 2013 open source scavenger app and ships a production-ready Droidcon hunt that adds QR fallback for non‑NFC phones, Material Design UI, Play Game Services achievements and leaderboards, and event-specific hunts served from a central backend. Backend is written in Golang + Gin with MongoDB storage, admin UI built in Dart/Polymer, source on GitHub and Android app on Play Store. Deployed at multiple events (droidcon UK 2014, C Motion) and plans include iOS support and Cardboard VR clues.
