Hello,
I have worked on many dashboard design which includes google analytics Dashboard, Mail Campaign Tracking Dashboard and many more. I am also expert in Data base design and create code and database schema in such a way that there is always scope of expansion. More over I have worked in one of project where it required role base access to pages, these role can be create, update an configure from UI Screen. Also multiple role could be assigned to single user. So I have capability to everything you need

2. Database Design for future expansion
3. User and Role Management.
4. Responsive design for mobile user as well
Do let me know how we can start the work. Let me known in case of quires.
