web app developer

New Web app to be developed from scratch, ideally on Bubblle.io, but open to other platforms as long as full functionality can be achieved.
I have already built a demo/prototype of the website/web app on Wix, but not all functionality can be achieved, so need to start again from development, but i am happy with the design i have already created.
I believe the website will require 5-8 pages, including index / sign up forms / landing page / member profile page.
The project will also require some API integrations - primarily with LinkedIn, Automation, and basic tracking and reporting for members that sign up to the platform.
