With a small team, I develop and troubleshoot the core Ruby on Rails API for a print-on-demand & package fulfillment textile manufacturer. Our JSON API handles both the B2B customer-facing order requests, as well as the internal factory-facing transactions between the corporate ERP, a legacy .NET SOAP application, and the factory floor web application. We are constantly adding and optimizing API endpoints to handle new types of customers and changing business needs. As a global company with manufacturing centers in the US, Mexico and Europe, we are also always updating API integrations with all of the largest global shipping and fulfillment API's.
