During January 2026, Yew Jun developed a partner trading fee calculation feature for the Bags App within the DefiLlama/dimension-adapters repository. He implemented logic to derive partner fees from DBC swaps, updating the SQL layer to aggregate new fee metrics and adjusting fetch logic to accommodate protocol changes. This work enabled more accurate revenue attribution and improved transparency for partners by providing near real-time reporting. Utilizing SQL and TypeScript, Yew Jun focused on backend development and database management, demonstrating depth in protocol integration and data-fetch pipeline optimization. The feature addressed manual reconciliation challenges and enhanced the reliability of partner fee reporting.
