Hi I’m a real human and experienced in both Flutter (Dart) and React Native (JavaScript/TypeScript), with hands-on delivery of production apps for iOS and Android. The main technical challenge in your stack is ensuring every feature compiles and performs consistently across both frameworks while supporting fast bug fixes and a clean architecture for future modules. I address this through disciplined state management, platform-aware components, and API-driven workflows that keep parity between Flutter and RN builds. I have full Xcode experience and a MacBook, enabling me to publish TestFlight builds and maintain iOS pipelines without blockers. My background includes REST/GraphQL integrations, unit testing, CI/CD usage, and active participation in GitHub code reviews. I’m fully available in US time zones with weekend coverage, ready to handle your urgent fixes and continue into long-term sprints. I’m confident I can contribute immediately while maintaining stability and scalability across both apps. Thanks, Hercules

@kareemmaize

I'm a real human Hi there To step into a live multi-platform environment and ship urgent fixes safely, the most critical part is understanding your build pipeline and existing architecture before touching production code. I work comfortably in both Flutter (Dart) and React Native (TypeScript), ensuring features compile cleanly on iOS and Android from the first build. I also have Xcode experience, a MacBook, and can handle TestFlight builds, provisioning profiles, and App Store submissions without delays. For urgent bug squashes, I typically start by reproducing issues locally, validating logs, and isolating root causes before pushing minimal, stable fixes. From there, I integrate clean modules with proper state management and API handling, plus unit tests where needed. I’m fully aligned with US (NY) time and weekend availability. Once I review your repo and immediate priorities, I’ll confirm sprint velocity and delivery targets clearly.

I’d love to jump in and start clearing these milestones with your team. Warm Regards, Farhin B.

@rajubhalani

Lucijana, for your urgent need for an experienced developer proficient in Flutter and React Native for multiplatform mobile development, would it be fine if I review your current bug fixes and new module requirements first, then suggest a seamless approach for compiling and optimizing features across iOS and Android platforms? So I believe that by efficiently addressing the immediate bug fixes and new module, we can establish a solid foundation for a successful ongoing collaboration, ensuring smooth performance and clean compilation for all future features. By the way, do you have a preferred timeline in mind for clearing the initial milestone and transitioning into the regular sprint cycle?

@kishanbwts

I'm a real human I’ve tackled urgent bug fixes and features on both Flutter and React Native apps running on iOS and Android, making sure each build runs clean from day one. One project involved coordinating quick turnarounds on a React Native app for an e-commerce client while syncing with backend GraphQL APIs, which sounds close to what you need. I have full Xcode experience and a MacBook ready for publishing builds and managing TestFlight. Do you already have a CI/CD setup for deploying these builds, or would you prefer to handle this manually for now? Also, for the new module—are there existing designs or specs you can share to speed up development? I can start immediately to handle your urgent bug squashes and new features, then smoothly move into your sprint cycles with code reviews and tests. Ready to jump in and get your apps stable and shipping.

@waqaswebmaster

I’m a real human I can jump in immediately on urgent bug fixes and ship a small module across both Flutter and React Native with clean iOS/Android builds, then stay on for ongoing sprints (REST/GraphQL integrations, unit tests, GitHub PR reviews, and release support). I’m comfortable working NY-time and weekends when a release needs it. I also have Xcode experience and can handle iOS build/signing tasks, TestFlight uploads, and troubleshooting CI/build issues. I’ll start by reproducing the bugs, isolating root causes, patching with minimal regression risk, and shipping via a tight PR cycle with clear notes. Then we align on architecture, coding standards, and a predictable sprint workflow. Share the repo access + current blockers and I’ll begin right away. Best regards, Waqas
