I am looking for an experienced mobile app developer to fix one specific bug in an existing review and rating application for iOS and Android. The app is already developed, so this is not a full app development project. The issue may be related to phone-number OTP login, star ratings, text reviews, image or video uploads, push notifications, average rating calculations, moderation tools, API communication, or build errors. I will provide the source code, error details, screenshots, logs, and steps to reproduce the problem. The developer must identify the root cause, fix the issue without affecting existing features, test the affected functionality, and provide the updated source code with a brief explanation of the changes. The fixed budget is $10 USD for one small and clearly defined bug. Additional bugs or new features will be handled separately. The task should be completed within one day. Please apply only if you have experience with Flutter or React Native, can start immediately, and accept the $10 fixed budget.

Hi, I carefully reviewed your complete requirements, including diagnosing a single bug in your existing review and rating app, identifying the root cause, applying a safe fix without affecting existing functionality, testing the affected module, and delivering the updated source code with a brief explanation of the changes. I have reviewed everything, and I have similar work and a detailed proposal that I can share during our discussion. Our team has extensive experience debugging Flutter and React Native applications, including OTP authentication, API integration, push notifications, build issues, media uploads, ratings and review modules, and platform-specific issues on both Android and iOS. We focus on identifying the actual root cause rather than applying temporary fixes. We'll review the logs, reproduce the issue, implement the fix, perform regression testing on the affected functionality, and provide clean, documented changes. If this bug is truly a small, isolated issue as described, we can start immediately and complete it within your one-day timeline. One quick question: is the application built with Flutter or React Native, and could you briefly describe the specific bug you're experiencing? Looking forward to working with you.

I can start immediately and help identify the root cause by reviewing the source code, logs, screenshots, and reproduction steps. Whether the issue is related to OTP login, ratings logic, API calls, uploads, notifications, or build errors, I will isolate it and fix it without affecting existing functionality. I have experience working with both Flutter and React Native, including debugging API integrations, authentication flows, and app performance issues. After fixing, I will test the affected module and provide the updated source code with a clear explanation of changes. Can you share which exact bug needs to be fixed first? Thank you.

Hi, I understand you need one specific bug fixed in an existing review and rating app without impacting the current functionality. I have experience working on Flutter-based mobile applications, API integrations, authentication flows, notifications, media uploads, and production bug fixing. Most of my recent work involves identifying root causes quickly and delivering safe fixes in existing codebases rather than rebuilding features. I'll first reproduce the issue using the logs, screenshots, and steps you provide. I'll isolate the root cause and implement the fix with minimal impact on the existing application. I'll test the affected flow thoroughly and share the updated source code along with a short explanation of the changes made. Could you confirm whether the project is built in Flutter or React Native? Also, is this a release-build issue or reproducible in the development environment as well? I can start immediately and deliver within the requested timeline.

Hi, bugs in review and rating apps usually trace back to one of three places: the rating submission logic, API response handling, or state not syncing properly between the app and the PHP backend. I'll start by reproducing the bug on my end, then trace it through the React Native or Flutter layer down to the API call and fix it at the root, not just patch over it. I'll verify the fix on both iOS and Android before handing anything back. You'll get a screen recording showing the bug resolved and working correctly. Can have this done today. What exactly is it doing, is it a crash, wrong data being saved, or something not displaying right? Regards, Imtiaz, SecureTechs

Hello, The app likely fails due to inconsistent OTP/session handling or an async state-management race in the rating/upload flows causing dropped responses or failed saves. I will reproduce the bug, fix the problematic async flow and API error handling, add focused tests for the affected screens, and deliver the updated source with a brief changelog within the day. I fixed a Flutter reviews app where OTP tokens expired during login (restored reliable login and rating persistence) and patched image upload retries in a React Native marketplace app with verified results. I also recommend adding lightweight logs for upload/rating failures to catch regressions faster. If that plan works for you I'll start immediately and deliver the patched source and changelog within the day. Thank you, - Bohdan
