Worked on enhancing delivery query capabilities within the hyperledger-labs/fabric-token-sdk repository, focusing on backend development using Go. Delivered a targeted feature expansion that introduced a Delivery field to the DeliveryScanQueryByID function, enabling more precise querying and improved tracking of delivery data. The approach centered on a single, low-risk commit to ensure stability and maintain traceability, while enriching the underlying data structures to support more robust analytics and lookup operations. No bug fixes were required during this period, reflecting a focused and stable codebase. The work improved operational visibility and streamlined workflows for delivery-related queries within the system.
