Worked on HathorNetwork/hathor-core to enhance the NanoContractHistoryResource by adding an order parameter, allowing clients to retrieve transaction histories in either ascending or descending order based on timestamps. This server-side feature, implemented in Python, improved API flexibility and reduced the need for client-side sorting, streamlining data presentation for dashboards, audits, and analytics. Focused on backend development and API design, the work emphasized robust testing to ensure reliability and maintainability. Although no bugs were fixed during this period, the contribution strengthened the user experience for history-related queries and provided clearer traceability for changes within the transaction history resource.
