Developed and delivered a Kreo Fees Adapter System for the DefiLlama/dimension-adapters repository, focusing on automated fee collection and structured revenue reporting for USDC.e on the Polygon network. The work involved designing a scalable, reusable adapter pattern in TypeScript to streamline future integrations and minimize onboarding time for additional assets. Leveraging backend development and API integration skills, the implementation enabled daily ingestion of wallet data and generation of auditable revenue outputs, supporting enhanced financial reporting and governance. The solution also included precise address pinning and historical data alignment, ensuring accurate attribution and reproducibility for both audits and ongoing partner revenue visibility.
