My cross-platform sports game (live on both iOS and Android) needs its next big push. I am ready to roll out real-time multiplayer and, while we’re in the codebase, to tidy up the overall experience. Here is what I’d like delivered: • Multiplayer support – end-to-end implementation, from the matchmaking screen through to stable real-time play and basic leaderboards. • UI refresh – polish menus, scoreboards and on-screen controls so they feel modern and consistent across devices. • Performance tuning & bug fixes – smoother frame rates, shorter load times and elimination of the nagging crashes and logic glitches reported in the current build. You’ll be working with the existing project for both iOS and Android, so the final build must ship cleanly to the App Store and Google Play without introducing new regressions. I will provide current source, crash logs and my test cases. A short testflight / internal release for verification is part of the hand-off. If you have a proven track record adding multiplayer to mobile games and a sharp eye for interface and performance, let’s talk timelines and milestones.
