Simon Laplace enhanced the HathorNetwork/hathor-core repository by implementing a server-side order parameter for the NanoContractHistoryResource API. Using Python and leveraging backend development and testing skills, Simon enabled clients to retrieve transaction histories in either ascending or descending order by timestamp. This feature reduces the need for client-side sorting, streamlining data presentation for dashboards, audits, and analytics. The work focused on improving API flexibility and user experience for history-related queries, while also strengthening traceability of changes. Over the course of the month, Simon delivered this targeted feature, demonstrating depth in API design and backend implementation without addressing bug fixes.
