Hi,
I have read your description carefully I understood your want.
Since 2012, I've started mobile application development for iOS & Android. In the meantime, I've learned lots of mobile programming languages such as Swift, Objective C, Ionic, React Native and Java.
I've made tons of apps such as Photo Sharing App, Social App, Photo Editing App, Uber-like App, Chat App, Contact Sharing App, Shopping App and so on.

Actually, I don't have any other project so that I can work full time on your project. We can discuss it as well in English whenever you want.
I promise with you that I will provide a qualified product in the timeline. I will refund fully if you are not happy with my result.
Best regards.
