Create a simple React Native package and Integrate in Native IOS and Android Apps as versioned package.

I have existing native apps on both iOS and Android that require the integration of React Native as a bundled package.

The freelancer should be proficient in:
- React Native
- iOS and Android native app development (Swift/Kotlin)
- React Native integration into native apps

I am looking to do similar to what is explained in this video. It can be as simple code as possible.

1. Create simple Standalone react native app without IOS and android folder. It can be hello world code with simple Button. Build android and IOS bundles. You do not need to publish you can keep them on you computer locally and integrate using local path. You can publish package if you are comfortable.
2. Add React native into IOS and Android native apps
3. Link Standalone project react native created bundles into native IOS and Android apps.
4. Integrate Standalone project react native successfully into native IOS and Android apps by calling main app from the react native app via activities or native bridges.
