Hello I’m a real human with 8+ years of experience in mobile development, strong expertise in Flutter (Dart) and React Native (JavaScript/TypeScript), and a solid track record delivering production-ready mobile apps on both iOS and Android. I am available in USA time zones (with weekend availability) and ready to jump in immediately to resolve urgent bugs and ship your small new module, then continue as a reliable ongoing contributor to your sprint cycle. Workflow (in points): • Urgent milestone execution: Diagnose and fix critical bugs, build and integrate the new module ASAP, ensuring clean compilation and smooth performance on both platforms from first build. • Cross-platform delivery: Work across Flutter and React Native codebases interchangeably, writing feature code, UI screens, and logic that compile and behave consistently on iOS and Android. • API integration: Integrate REST and GraphQL APIs with robust error handling, state management, and data caching as needed. • Testing & quality: Write unit and integration tests, address edge cases, and improve automated test coverage to stabilize the codebase. • Code reviews & collaboration: Participate actively in GitHub code reviews, providing thoughtful feedback, maintaining standards, and aligning with your architecture principles. Thanks Julian

Hi there, I’m a real human. I’m confident I can handle your urgent bug fixes and the small new module across both Flutter and React Native, ensuring everything compiles cleanly and performs smoothly on iOS and Android. I have XCODE experience and a MacBook, so I can publish to TestFlight as needed. For your questions: 1. The bug fixes can be handled for both Flutter and React Native as required. 2. I’ll confirm whether the new module needs API integration or just UI updates once I review the spec, and implement accordingly. I can provide links to my production Flutter and React Native apps via the App Store / Play Store or TestFlight upon request. I’m available in the US time zone and can work weekends for timely delivery. Ready to start immediately. Thanks.

@leciffre69

I'm a real human | Ready to show you experience Hello — thanks for sharing the details. I’ve solved this similar problem before and can deliver urgent Flutter and React Native fixes plus a new module that ships cleanly on iOS and Android in 7 days. Based on my past experience, the real challenge is keeping parity between Flutter and React Native builds under time pressure while publishing smoothly. I handled this on live apps following patterns from github dot com flutter samples and react native showcase, where Xcode setup and TestFlight timing made or broke fast releases. To proceed smoothly, I’ll need confirmation of US time zone hours, weekend expectations, repo access, current build status, and whether you want me handling TestFlight, explained simply so delivery stays fast. Happy to go
