Alex Jungean
About this gig
Is your React Native or Expo app crashing, failing to build, or breaking in a key user flow?
I diagnose and fix defined issues in existing React Native, Expo, TypeScript, Android, and iOS projects.
This Gig can cover:
- runtime bugs and app crashes
- Expo or EAS build errors
- package and dependency problems
- login, API, or backend connection issues
- push notification problems
- navigation and state bugs
- responsive mobile UI issues
- Android or iOS configuration within the agreed scope
I have delivered production mobile platforms for fleet management, a services marketplace, and city discovery, using React Native, Expo, APIs, databases, notifications, maps, and multi-language interfaces.
Before ordering:
Send the exact error, reproduction steps, Expo and React Native versions, target platform, and expected behavior before ordering.
New screens, redesigns, SDK migrations, payments, store submission, or complete mobile apps require a custom offer.

FAQ
Can you fix both Android and iOS issues?
Yes, depending on the issue, available test environment, source code, accounts, and required native tooling. Send the affected platform and reproduction steps first.
Can you fix Expo or EAS build failures?
Yes, for a defined failure with logs and reproducible configuration. Apple certificates, provisioning, Google signing, and account permissions must be available when relevant.
Can you upgrade my Expo SDK?
An SDK upgrade can affect many dependencies and native settings. I first assess the project, then provide a custom offer for the migration and testing.
Can you publish the app?
I can provide preparation or submission assistance as an extra. The buyer provides developer accounts and fees. Apple and Google control review and approval.
Can you add a new feature?
Yes through a custom offer after reviewing the design, flow, backend, and platform impact. A new feature is not a revision to a bug fix.
What counts as a revision?
A revision corrects the agreed fix. A new crash, feature, platform, build target, or changed requirement is additional scope.
