React Admin User Interface/Dashboard Design

I have a React Native App (IOS and Android) with React Backend. I need a Professional React UX/UI Designer to improve the look and feel of the Admin Backend. You must be able to work with the current App Developer to integrate the codes seamlessly without changing the Apps. Please see samples of the kind of UI and Layout we need here: https://www.youtube.com/watch?v=c313KkNuRvk
