Kith.com Program (Shopify Knowledge)

I am looking for a programmer who can build a Microsoft program that can add a product and checkout a product on [login to view URL] in seconds. The key to this program is SPEED. The reason I say this is because the products the program will be trying to add to cart and checkout in seconds sell out very fast within the matter of seconds obviously. The program must be able to run many tasks and also have proxy support. It is imperative to know [login to view URL] is a Shopify website and the programmer should have a good knowledge with how they work including product variants and product ID's. The program should have a keyword monitor on it so that it can be searching for these products that are to be uploaded on the website every second! The monitor will be on the actual title of the webpage of the product I am trying to purchase rather than the actual url. The reason for this is because the product url will usually have a different product name than the title of the product on that page to throw off programs like such! It is imperative to know SPEED and proxy support is everything. There also happens to sometimes be a "QUEUE" which is like a wait in line system right when these products release and a user tries to check out manually. A bypass would be huge and it has to deal with the cookies and settings such that once you get through this queue on one user you can get through on all the other users and try attaining multiple pairs!
