I have developed a mobile application using React Native and need assistance in finalizing and publishing it on the Google Play Store and Apple App Store.

Scope of Work:

Google Play Store:

Generate an AAB (Android App Bundle) file for the app.
Ensure the app is signed with the correct keystore and aligned with Google Play's requirements.
Prepare and upload the app to the Google Play Console.
Assist in filling out required details such as app description, screenshots, privacy policy, etc.
Ensure the app complies with Google Play's guidelines for approval.
Apple App Store:

Generate an IPA (iOS App Archive) file for the app.
Ensure the app is signed with the correct provisioning profile and certificate using Xcode.
Prepare and upload the app to App Store Connect.
Assist in providing details like app description, screenshots, and privacy policy.
Handle any requirements for Apple’s review process to ensure the app gets approved.
Requirements:

Experience with React Native and mobile app deployment.
Familiarity with creating AAB and IPA files.
Knowledge of Google Play Console and App Store Connect processes.
Ability to troubleshoot and handle errors or rejection issues from the stores.
Clear communication to ensure a smooth process.
Please provide examples of previous apps you have successfully deployed on both platforms and your estimated timeline for completion.
