Every project is different. Packages cover one clearly defined issue, not unlimited fixes or a complete app upgrade.

FAQ
What do you need to start fixing my app?
Please share your React Native version, iOS or Android platform, error logs, screenshots, and a short description of the issue. Repository access may be needed after we agree on the scope.
Can you fix any React Native issue for $90?
The Basic package covers one small, clearly defined bug. More complex issues, native build errors, or major React Native upgrades may require additional investigation. Please contact me first so I can review your issue and provide an accurate estimate.
Can you fix iOS Xcode and Android Gradle build errors?
Yes! We work with Xcode, CocoaPods, Gradle, Hermes, native modules, and dependency conflicts. Send us your build logs so we can investigate the issue and estimate the effort.
Can you upgrade my app to the latest React Native version?
Yes. We handle React Native upgrades, dependency updates, native module compatibility, and build fixes. The cost depends on your current version, project complexity, and required changes.
Will I receive the updated source code?
Absolutely! You'll receive the updated source code or a Git commit with the agreed fixes. We can also explain what caused the issue and what was changed.
Do you test the app after fixing the issue?
Yes. We test the agreed fix on the relevant platform and verify that it works as expected. Full regression testing across all devices and features is available as an additional service.
Can you fix bugs in an app developed by another team?
Of course! We regularly work with existing React Native codebases. We can investigate crashes, API issues, outdated dependencies, and compatibility problems without rebuilding your app from scratch.
Do you offer long-term React Native maintenance?
Yes! Our team provides ongoing React Native maintenance, performance optimization, version upgrades, API integrations, and App Store or Google Play release support. Contact me to discuss your needs.
