Urgent Multiplatform Mobile Developer Wanted

@Microlent

I’m a real human I’m experienced with both Flutter and React Native, delivering production apps that run cleanly on iOS and Android from the first build. I’m comfortable fixing urgent bugs, shipping small modules fast, and then moving into a steady sprint cycle with API integrations, testing, and GitHub reviews. I can work in the US time zone and I’m available on weekends for urgent releases. I have hands-on Xcode experience and use a MacBook for TestFlight builds and store submissions. I can share live Flutter and React Native apps from the App Store and TestFlight to show real production work. Ready to start immediately and stay long-term. Best, Jenifer

@leadconcept

Greetings, I understand you need an experienced mobile developer proficient in both Flutter (Dart) and React Native (JavaScript/TypeScript) for iOS and Android. The role requires immediate work on urgent bug fixes and a small new module, followed by ongoing sprint-based development including new screens, REST/GraphQL integration, unit tests, and code reviews. US time zone alignment and weekend availability are mandatory. Before we proceed, could you clarify, 1, Are there specific repositories or branches where the urgent bug fixes reside? 2, Should the new module follow existing UI/UX patterns or can improvements be suggested? 3, Are there CI/CD workflows in place for Flutter and React Native builds that we need to integrate with? Our team includes developers with production experience in both Flutter and React Native, fully capable of delivering cross-platform features with clean builds, GitHub collaboration, and Xcode/TestFlight management on Mac. We focus on rapid delivery for urgent milestones and long-term, maintainable mobile app development. Let us connect to confirm project scope, access, and timelines. The current bid amount is a placeholder to start the conversation. Regards Yasir LEADconcept PS: I can provide live Flutter and React Native apps we’ve shipped for review, along with TestFlight links if needed.

@Zeeshan0489

Hi there, I'm a real human I’ve read your urgent multiplatform mobile project and I’m confident I can squash bugs quickly and ship a small new module for both Flutter and React Native on iOS and Android, with builds that compile cleanly on first try. I bring production Flutter and RN experience and have delivered apps with REST/GraphQL integrations, unit tests, and GitHub code reviews. I’ll start with immediate triage: reproduce issues from the backlog, implement fixes, add automated tests where feasible, and ship the new module in the shortest feasible window. Then I’ll align with your sprint cadence for ongoing work—new screens, API integrations, tests, and peer reviews. I do have Xcode experience, and I have a MacBook to publish TestFlight builds. I’ll operate in US time and am available weekends for critical milestones. Initial milestone proposal: bug squashes + small module within 2 days; then we roll into regular sprints. If you’d like to see live production examples, I can share access or links on request. Best regards,
