iPhone In-App Purchase Integration

I'm looking for a skilled developer to help me integrate in-app purchases on my iPhone app. The main details of the project include:

Stripe is integrated but app is rejected so just want that app should live with stripe.

- Offering non-consumable items (subscriptions) as in-app purchases.
- Utilizing an external payment gateway for the transactions, specifically Stripe.

In your bid, please outline:

- Your experience with integrating in-app purchases on iOS.
- Your familiarity with using Stripe as an external payment gateway.
- Any previous work or portfolio that showcases your experience with a similar project.

Your expertise in these areas is crucial to the success of this project. The ideal candidate will have a strong understanding of iOS development and experience in implementing secure and user-friendly in-app purchases.
