About this Gig
Your React Native or Expo app crashes, won't build, or got rejected by the store. I fix the root cause and explain in plain English what was wrong and what changed.
I've worked in React Native for nearly 5 years, including at a truck-hiring logistics platform and now at a nationwide retail chain, where I work on an Expo SDK 54 / React Native 0.81 app. I've shipped iOS and Android releases via TestFlight, the App Store and Google Play.
What I fix:
- Crashes, red screens and blank screens
- Android (Gradle), iOS (Xcode) and EAS build failures
- Dependency conflicts and failed installs
- Expo SDK and React Native version upgrades
- New Architecture migration, required from React Native 0.82 and Expo SDK 55
- App Store and Play Store rejections: fixes and resubmission
- Apps built with Cursor, Claude Code, Bolt or Rork that work in the demo but break on real devices. I use Claude Code and Cursor daily, so I can read and clean up what they generate.
Before ordering, send me the error, logs or rejection notice and I'll confirm scope and package.
Store approval itself is decided by Apple and Google.
FAQ
Which package should I order?
Message me first with the error, logs or a short screen recording. I'll tell you which package fits, or send a custom offer if it's bigger. Basic covers up to 3 well-defined issues. Standard is up to 8 issues or one version upgrade. Premium is a major upgrade with store resubmission.
Can you guarantee App Store or Play Store approval?
No. Review decisions belong to Apple and Google. I fix each point in the review notes that can be solved in code, build settings or the store listing, then resubmit (included in Premium, an add-on otherwise) with a reply to the reviewer explaining the changes.
My app was built with Cursor, Bolt or Rork. Can you work on it?
Yes, as long as it's React Native or Expo. I read the code first, fix what's broken, and list the risky parts I find (exposed keys, missing error handling, no loading or empty states) so you know what's left. I use Claude Code and Cursor daily in my own work.
What is the New Architecture and do I need it?
It's React Native's current rendering and native-module system. React Native 0.82+ and Expo SDK 55+ can't run the old one, so staying current means migrating. Most of the work is usually updating or replacing libraries that don't support it yet.
What access do you need?
Your code (a repo invite or a zip), the exact error or logs, and steps to reproduce. For build or store work, a team invite on Expo/EAS and a user invite on App Store Connect or Play Console. I never need your account passwords.
Will you test on both iOS and Android?
Yes, on every platform the issue touches. I check the fix on simulator or emulator, and where it matters I make a TestFlight or Play internal testing build so you can try it on your own phone before release.
What if the fix turns out bigger than the package?
I tell you as soon as I know, before doing extra work, and explain why. You choose: stop there with what's done, or accept a custom offer for the rest. No surprise charges.
Do I get the source code and an explanation?
Yes. You get the changed code as a pull request or zip, plus a short note on the root cause and what changed, so your next developer or AI tool can follow it.
