Create and develop a WEB app

Description

I don't need a shop or store built...
I need the back end for the product... For example if you go to this link here :https://turninghearts.com/
Then scan the QR code on the page banner... it will open up a profile for the person that its in memory of. You can then see the features that the profile has, such as bio, pictures, videos, tributes (like a facebook profile wall)
I need someone to be able to build this including ALL the features.
- The shop front you don't need to develop ...
1. Customer Purchases Product: The customer visits the website shop and purchases a product.
2. Automatic QR Code Generation: Upon purchase, a unique QR code is automatically generated and linked to the customer's profile.
3. QR Code Printing: The QR code is then printed onto the purchased product or included in the packaging.
4. Product Sent to Customer: The product, along with the printed QR code, is sent to the customer.
5. Profile Setup: Upon receiving the product, the customer can scan the QR code using a smartphone or QR code scanner. This action directs them to set up their profile associated with the purchased product.
6. Profile Features: Once the profile is set up, users can access it by scanning the QR code again. The profile may include details such as biography, photos, videos, and the ability to leave tributes or interact with the product in other ways.
In essence, the QR code serves as a convenient link between the physical product and its associated digital profile, allowing customers to easily access additional information and features related to their purchase.
