eBook Reader app

I am looking for someone to develop an eBook Reader app for both iOS and Android. It should feature offline reading, ability to set bookmarks and highlights, and text-to-speech functionality. The app design should be minimalistic. You will handle the full challenge of development, including UI/UX design, coding, and testing. I am looking for someone who is well-versed in developing apps for both iOS and Android, and is committed to producing a quality and user-friendly product.
