App Development

I am looking for an experienced app developer to create an app for both iOS and Android platforms. While I do not have a preferred programming language or framework, I am open to suggestions from the developer. The app should include in-app purchases as a feature. Additionally, I would like social media integration and push notifications to be considered as possible features. Ideal candidates for this project would have experience in app development for both iOS and Android platforms, as well as a strong understanding of in-app purchase integration.
