    Hello Greetings , An new idea, I was reading on your description and through this course, feeling very interest in your project. Of course, I have the rich experience in development of social apps as big as dating app or E-commerce app , photo sharing app and so on. In particular, at the mobile company I have developed the decades of apps as consumers' requirements, so think that we can create a successful Co-operation for both of us. As I work with excellent designers and web guys together, there is no any obstacle during developing. The important factor is that we should be on same page for safe contract, based on high trust of each other, In technical side, that we should have unique opinion for beautiful design, smooth usage sensor and reliable quality guarantee. For this, can you provide app details and corresponding mock up from you? Finally you will get the best result in the shortest time with the reasonable budget. Hopefully discussing the project with you soon...
