Skills required will likely need advanced API/data-laking knowledge, NodeJS (for Steam Bots - (Specifically requesting counter-strike items that have been selected on the website), as well as integration into our website using further Coinbase/PayPal APIs.
In short - the project in question is an automated Counter-Strike (a computer game), which has virtual items. Our website will buy these items automatically. A user will sign into the website using "Steam" (Steam Community), set their "trade-URL" and can select items that they own. Using our own API, we set prices based on other APIs (this part is already done - albeit very manual), and will match items in the user's inventory. Once the user selects everything they wish to sell, we then send a trade offer using the Steam trading bot, and once the trade has been confirmed - we then initiate a payment that was defined on the website.
