Worked on enhancing DeFi analytics within the DefiLlama-Adapters and dimension-adapters repositories, focusing on improving TVL accuracy, revenue tracking, and adapter modernization. Addressed TVL calculation issues by refining contract property access and eliminating double-counting across protocols. Migrated the Quickswap V2 Polygon adapter from a deprecated subgraph to an on-chain log-based approach, standardizing fee configuration and leveraging shared helpers. Implemented fee and revenue tracking enhancements for TurboFlow and ensured accurate fee attribution for migrated USDai loans using GraphQL and ABI parsing. Utilized JavaScript, TypeScript, and Node.js to deliver five new features and resolve two bugs, emphasizing robust data integration and backend reliability.
