Mobile Design Review

Hi, I am looking for a mobile designer to review some rough mock-ups of an App I have done. I need someone to come back with suggestions and recommendations on the UI & UX that promotes a good customer experience. The application must be fun, interesting, easy to use and understand.

Must Haves:
Exp with 3rd party libraries & Api's
Up to date on the latest mobile app design & tech trends

Please share portfolio of released applications
