Lorenzo Mascia worked on the openfoodfacts/smooth-app repository, delivering a dedicated UI/UX overhaul for the Hunger Games feature. He migrated the interface from an overlay to a full page view, enhancing integration and consistency within the mobile application. Using Flutter and Dart, Lorenzo refined image thumbnails and question cards to improve clarity and presentation, while also redesigning the navigation flow to reduce user friction when opening or closing question pages. This architectural shift not only improved usability but also laid the groundwork for better testability and maintainability, enabling smoother future enhancements and a more robust user experience in mobile development.
