mobile app

I'm looking for a mobile app developer mumbai based to create a great customer interaction experience for my users. For this project, I'll need the app developed for both iOS and Android operating systems. I already have everything from designs to wireframes ready to go so the developer has a comprehensive and detailed understanding of what is to be included in the app. The main function of the app will be customer interaction, but I'm also looking for developers who can create an attractive and functional user interface. Knowledge of the latest advancements in mobile technology would be a plus.
