Senior Full Stack Developer – Internal Operations Platform (eBay API, Barcode Scanning, Inventory)

We are a growing eCommerce business specializing in HVAC parts and are looking for a long-term development partner to help build an internal operations platform. The first phase of the project focuses on reducing the time required to create eBay listings using barcode scanning, predefined product templates, photo capture, and integration with the eBay Sell APIs. This is not a marketing website. We're building software that our warehouse team will use every day. The ideal candidate has experience building internal business applications involving inventory management, barcode scanning, REST APIs, warehouse workflows, or eCommerce operations. We expect this project to evolve over time into a broader internal operating platform including inventory management, warehouse locations, shipping workflows, and integrations with systems such as Cin7. About TrueSpec We're building more than an internal listing tool. We view this application as the foundation of our company's operating platform. While the first phase focuses on eBay listing automation, future phases may include inventory management, warehouse locations, shipping, refurbishment tracking, reporting, and integration with ERP/IMS systems. We're looking for a developer who enjoys solving operational problems and wants to help build software that will grow with our business.
