I’m building a full-featured cross-platform mobile application and am looking for an experienced Flutter developer who can take the product from prototype to store-ready builds for both iOS and Android. The core of the role is to architect and develop a clean, scalable Flutter codebase that delivers a smooth, reliable user experience across platforms. While the overall design direction and data structure are already defined, I’m keen to collaborate on workflow decisions such as app navigation, state management, and third-party service integrations. If you have strong opinions on Riverpod vs Bloc, or hands-on experience integrating payment systems, APIs, authentication, or other third-party SDKs in Flutter, I’d love to discuss the approach and trade-offs. Key milestones • Initial Flutter project setup with adaptive UI for iOS and Android • Core application flows implemented (screens, data handling, user actions) • Final polish, QA, and store-ready builds for App Store and Google Play Acceptance criteria • Clean, well-documented Dart code following Flutter best practices • Responsive layouts tested on recent iOS and Android devices • Stable user flows with proper error handling and performance optimization If you’ve shipped production Flutter apps before, please share a GitHub repo, portfolio, or store link. Also include your preferred architecture, estimated timeline, and any questions you’d like clarified before we get started.
