FAQ
What is considered one bug?
One bug is one clearly defined and reproducible issue affecting a specific feature or flow. Multiple errors caused by the same root problem may be treated as one bug after investigation.
Can you fix both Android and iOS issues?
Yes. I can investigate React Native issues on Android and iOS. The Basic package covers one agreed platform, while broader cross-platform testing is included in higher packages.
Can you fix Android Gradle build errors?
Yes. I can investigate Gradle, SDK, manifest, dependency, signing and native-module configuration errors. Complex upgrades may require a custom offer.
Can you fix iOS Xcode and CocoaPods errors?
Yes. I can investigate Xcode, CocoaPods, deployment-target, signing and native-module configuration issues. Access to a suitable macOS environment may be required.
Can you optimize my app’s performance?
Yes. I can investigate unnecessary re-renders, slow lists, large images, loading states, memory-related problems and inefficient component logic. Major architecture refactoring requires a custom offer.
Do you add new features in this Gig?
No. This Gig is primarily for fixing and optimizing existing functionality. New screens, features or integrations should be discussed separately.
Will you provide the updated source code?
Yes. You will receive the updated source code for all changes included in the agreed order scope.
