Developed the Unclaimed Development Fund Coupons Listing feature for the hyperledger-labs/splice repository, focusing on backend enhancements and API development using Scala. The work involved updating the scan proxy logic and expanding the API surface to support listing unclaimed development fund coupons, which streamlines reconciliation and governance processes by reducing manual checks. Integration testing was implemented to ensure end-to-end reliability and improve test coverage for the new functionality. All contributions adhered to CIP-82 guidelines and project QA standards, with signed-off commits ready for review. The scope was concentrated on a single feature, demonstrating depth in backend integration and response handling.
