Flutter Developer - iOS / Android Game

We're building an original American-style crossword game for iOS and Android in Flutter, launching in five languages. The build covers the crossword engine and UI, a puzzle generation system, a backend and admin panel, progression with coins and streaks, a leaderboard, offline play, ads and in-app purchases, and store submission. The quality bar is high, so think polished casual puzzle titles from the bigger studios, especially on animation and smoothness. ***** This is a freelancer role, not an agency contract. Agencies need not apply. ***** What we need: 1. Solid Flutter and Dart experience with published apps 2. Comfortable owning implementation day to day, not waiting to be told what to type 3.
