Add a payment gateway to Shopify's Active Merchant(repost)

The project involves implementing a payment gateway to Active Merchant, the open source ruby library used by Shopify for payment processing. The quality of the work is important, since the plugin must comply with the? Payment Card Industry Data Security Standard (PCI DSS), available at? https://www.pcisecuritystandards.org. The developer that will be chosen should implement the available operations of the gateway in Active Merchant.? We are only looking for developers with experience in Ruby, preferably also with experience in Active Merchant. ## Deliverables The deliverables should be a fully functioning plugin for the Active Merchant library, preferably a git repository cloned from github ( <[login to view URL]>) The developer will be given a detailed API documentation about the payment gateway. This documentation should be all the technical information required to implement the plugin. The developer will be given a test account to test the payment gateway. When the plugin has been implemented, we will take over the management of the code and submit it to Active Merchant. The developer only needs to implement the gateway and prove that it works.
