About this Gig
Is your Flutter app crashing, slow, or rejected by the App Store? Let's fix it!
I'm Samiullah, a Flutter developer and Mobile Product Engineer with 6+ years of core tech experience. I specialize in flutter bug fix, deep debugging, architecture auditing, and high-level app optimization for Flutter & Dart applications.
No matter how messy the codebase is, I will clean it up and make it production-ready.
What This Gig Covers:
- Fixing critical app crashes & runtime errors
- Resolving complex State Management bugs (BLoC, Provider, GetX)
- Debugging broken API integration (REST, WebSockets, Firebase)
- UI/UX rendering layout fixes & multi-screen responsiveness
- Solving Android Gradle & iOS CocoaPods build/deployment issues
- App store optimization & policy rejection compliance fixes
The Performance Boost:
I don't just patch errors I optimize memory leaks, clean up technical debt, and ensure your app runs at a fluid 60fps.
Why Choose Me?
6+ years engineering background, native Android roots, strict Clean Code standards, fast turnaround, transparent communication.
NOTE: Please message me with your error logs or codebase access before ordering!

FAQ
Do you sign a Non-Disclosure Agreement (NDA) before looking at my codebase?
Absolutely! I highly respect your proprietary software and business logic. I am completely open to signing a strict NDA before you share access to your repository or error logs.
What access or files do I need to share to get started?
I will need access to your source code repository (GitHub/GitLab) or a zip file of the project. If the app is crashing under specific conditions, sharing error logs or a quick screen recording is highly recommended.
Can you fix iOS-specific CocoaPods or Android-specific Gradle build errors?
Yes. With my 6+ years of core engineering background, including extensive Native Android (Java/Kotlin) and iOS platform experience, I can easily diagnose and fix complex native-side build issues, architecture dependencies, and version mismatches.
My app is lagging and running slow. Can you boost its speed?
Definitely. I will perform a comprehensive performance audit to eliminate memory leaks, fix redundant state rebuilds (BLoC/Provider), optimize network API calls, and clean technical debt to ensure your app runs at a fluid 60fps.
My app was rejected by Google Play Store or Apple App Store. Can you fix it?
Yes. I will analyze the exact policy rejection notice sent by Apple or Google, modify the non-compliant code, update required permissions/metadata, and make the codebase 100% compliant with the latest store guidelines.
What state management frameworks do you support for debugging?
I have enterprise-level experience with all major Flutter state management ecosystems, including BLoC, Provider, Riverpod, and GetX. I ensure the bug is resolved while maintaining code modularity.
