Member-Based App with Book Shop

I'm looking for a member-based app that hosts a community of readers, a book shop with the author's books, and a membership entrance with personalized features. The app should be developed for both iOS and Android platforms, ensuring a seamless user experience across devices. The project involves creating a community platform with e-commerce features, requiring skills in backend and frontend development. Hello, my name is Yasho, I'm an author of multiple books in the spiritual, yoga, and devotional service niche. I have published over 80 books and I desire to build an app that hosts my reader community nicely. There should be an invitation to join the Bhakti Book Club membership, email login, a separate shop where all the books of mine are available (linked to amazon.com, or epubli.de) and a separate entrance for the reader to monthly new content, like new publications, video courses etc.
