Android App Porting to iOS

I need an experienced developer to port my Android app to iOS. The Android app is currently quite basic, mostly displaying information, but I would like to add some more advanced features to the iOS version. The core features that need to be replicated include user authentication, push notifications, and in-app purchases.

Ideal Skills:
- Proficient in Swift and Kotlin
- Experienced in cross-platform app development
- Knowledgeable in implementing push notifications and in-app purchases

Please, include in your bid examples of similar projects you've completed.
