Web application / software development

Hi, I'm looking for an experienced programmer to build a web application. It maybe useful to have experience in shopping carts, checkout processes, Stripe & paypal integration, account signup and login functions

I need the app to be functional, and look good

I attach instructions on the first phase of the project. There will be more phases to come

We already have some successful apps, but our current development team is too busy to take on anymore work.

Ideally I would like an ongoing relationship with the developer/development team to continue updating and maintaining the app but there is a chance you may have to handover to our current developers
