Worked on the hotwax/oms repository to deliver two major API feature sets focused on order management and product data access. Developed the Order Item Ship Group Management API, enabling creation, updating, and retrieval of ship groups for orders, which enhanced fulfillment control within the system. Expanded the Product Variants API by adding endpoints to retrieve product details and all associated variants, improving catalog data accessibility. Emphasized stable, maintainable endpoint design and consistent RESTful practices throughout the sprint. Utilized Java for backend development, applying skills in API development and order management systems to address operational needs and support future extensibility.
