Shopify App

I need a shopify app to be built. Here is the basic requirement Technical Requirement ------------------------------------- 1. Has to be done in asp mvc 5 2. Must use ShopifySharp for API call 3. Hardcore OOP design is needed App requirement -------------------------- The app is a bulk product edit app. It will be a small subset of this following app [login to view URL] But our app needs to edit only Product attributes but it must be designed in such a way so that we can extend your classes and make rules to bulk edit anything (almost), i.e. collection AGAIN, it must be built in a generic way so that if we need then we can use your framework and bulk edit other things as well. **All tasks must be scheduled. (you can use HangFire ) **Schedules are user specific (you do not have to build user authentication part, but use static user ids to show that it will work with any user authentication technic like identity framework of asp mvc 5) **schedule can be canceled or undone (the changes will revert back) NOTE REQUIRED ---------------------------- *Shopify handshake *Uninstall functionalities *Install functionalities *User authentication and management *Shopify Charge/Subscription management *We do not even need any front end for the app (Only a prototype UI showing that functionalities are working as required is enough) Thanks
