Adv app in ios and android -- 2

I am looking for an experienced app developer to create an advanced app for both iOS and Android platforms. The app should have user authentication as its main feature. Additionally, I am in need of a new design for the app. The ideal candidate should have expertise in app development across both platforms and be skilled in designing user-friendly interfaces. Experience with location-based services and in-app purchases is a plus.
