Dev for user role upgrade with product key

I'm looking for a Dev who can assist us in upgrading our website with the following custom element.

My company sells 2 different physical products, Product A and Product B, which are sold online and physical stores.
Both of them contain a direct Product Key, Product KEY A and Product KEY.
These product keys give access to the respective private pages where they will have access to various content depending on the purchased product.
(product key A gives access to private page A and product key B give access to private page B)

Today we just have a private page, where the client need to put the Product Key manually everytime as password.

However, we would like to create a member area, where the user create an account.
In this account the user write down the product key A or B. By writing down the product key, his role is automatically upgraded to user role A or B and can access the respective private pages each time they are logged in. They do not need to write down the product key overtime they want to access the private page, simply logged in with the registered product key

I need the memberarea to be integrated with woo commerce, so the clients member area have an overview of purchased product and so on, dashboard, shipping information and product key input.
