I’m looking for a developer who can build a single code-base mobile application with Flutter. My goal is to release the same app on both iOS and Android, so I need someone who is fully comfortable compiling, testing, and publishing to the App Store and Google Play. Flutter is my first choice—if you can demonstrate a clear advantage in switching to React Native I’m open to hearing it, but please be prepared to explain trade-offs in performance, UI consistency, and long-term maintenance. I’ll provide the full functional brief once we agree to move forward; for now, assume a typical feature set that will require: • Clean, well-documented Dart code • Responsive UI that adapts to current iOS and Android design guidelines • Integration with common back-end services (REST or GraphQL; final selection to be confirmed) • Basic analytics and crash reporting Acceptance criteria will include a fully running build on TestFlight and an Android release bundle, plus source code in a private Git repository. If you’ve shipped production Flutter apps to both stores before, I’d love to see your work and hear how you managed deployment, versioning, and post-launch updates. I made ai applications and marketplaces. I can make desktop application by python

Good to see this project, I will build your Flutter app from a single Dart codebase and handle the full cycle: responsive UI following both iOS and Android guidelines, REST or GraphQL integration, analytics, crash reporting, and publishing to TestFlight and Google Play. One thing that makes a real difference in cross-platform Flutter apps is setting up offline-first caching early. It keeps the experience smooth on spotty connections and saves you from reworking the data layer later. Questions: 1) Do you have a backend already, or will that need to be built alongside the app? 2) Are there any third-party services (payment, auth, push notifications) you already know you will need? I am happy to share two relevant production Flutter apps in our chat so you can see the build quality firsthand. Looking forward to your response. Best regards, Kamran

Hi, shipping one codebase to both stores is straightforward when the app boundaries are defined early, and I’ve built production systems where the real work is in keeping behavior consistent across release, analytics, and backend integration paths. The main engineering risk here is not the UI layer itself; it’s locking down app state, API contracts, and release behavior before the functional brief turns into platform-specific edge cases. The closest relevant project is AI-Driven Marketing Suite Development -- 2, where I worked in Flutter/FlutterFlow on a modular product with API-connected workflows and a documented handoff. Custom Feature Development & Integration is also relevant because it reflects how I approach codebase review, scoped enhancements, testing, and clean delivery. I usually structure apps around clear boundaries: presentation, state, service layer, and release configuration. That keeps REST or GraphQL interchangeable and makes analytics, crash reporting, and versioned builds easier to manage without coupling them to feature code. For production, I care most about failure handling, store-ready signing/configuration, environment separation, and update safety after launch. That is what determines whether a cross-platform app stays maintainable. If useful, I can review the functional brief and sketch the app architecture, risk areas, and release path for TestFlight and Android bundle delivery. Thanks, Hercules
