We are seeking a Shopify and Shipstation Go-To Developer to provide ongoing support and development for our e-commerce platform. The ideal candidate will have experience in integrating Shopify with Shipstation and optimizing workflows for efficiency. Responsibilities include troubleshooting, customizing, and enhancing our Shopify store and Shipstation setup. The role requires strong problem-solving skills and the ability to work independently. We are looking for someone to handle projects as they come up, on a long-term basis. TASK 1: Up until recently, our customers have always been charged the same carrier costs we are charged. No markup. However, recently customers are being quoted shipping costs at higher rates than we are charged. We want that changed back. TASK 2: We need a popup banner added to our website home page. We will provide the graphic. When responding, please provide a total cost for each of the 2 tasks separately, along with a timeline for completing the jobs.
