Hello, I've went through the attached document and I can can build a fully responsive and user friendly app (BBC) with admin panel to promote business and I will also add all the required functionalities, screens, member registration form and gallery in the app as per your requirements. I am senior mobile app developer and I am absolutely sure that I can do the project very well. Do you have reference design for the app?
Lets have a quick chat to discuss further.
I have extensive experience in designing and development of Websites, Mobile Applications, Management Systems and E-commerce or Online Stores Solutions.
