Two iOS React-Native Builds

I have a React Native code-base for different Android variants. I now need matching iOS versions compiled, prepared, and submitted to the App Store under my Apple Developer account.

Your job is to:
• configure each target in Xcode, create the correct bundle IDs, and handle certificates & provisioning profiles
• build Release IPA files that run smoothly on current iPhones and iPads

I will supply the existing repository plus any required assets and login credentials. Please have solid experience with React Native 0.6x+, Xcode, and App Store submission workflows. I’m ready to start as soon as you are; let me know your timeline and any information you’ll need.
