Developed and integrated new data capabilities for GrelfSwap within the DefiLlama/dimension-adapters and DefiLlama/defillama-server repositories, focusing on expanding daily volume and fee tracking for a Hedera-based DEX aggregator. Leveraged TypeScript and backend development skills to build scalable adapters that fetch and calculate trading volume, swap fees, and revenue, while also enhancing listing metadata with additional fields such as URL, symbol, and gecko_id. Refactored core data models and adapter logic to support future integrations and improve maintainability. The work emphasized robust API integration and data fetching, laying a foundation for more comprehensive analytics and streamlined future development.
