During November 2024, Ninemmdev developed cross-chain DEX adapter configurations for v2 and v3 within the DefiLlama/dimension-adapters repository, focusing on unified data collection for trading volume and fees across multiple blockchains. Leveraging TypeScript and data engineering skills, Ninemmdev implemented dex definitions, subgraph endpoints, and robust data-fetching logic to support multi-network analytics. The work enabled accurate, cross-network tracking of DEX metrics, improving visibility for DeFi stakeholders. All changes were thoroughly reviewed and passed testing standards, with no critical bugs reported. This feature laid a strong foundation for future expansion to additional networks and DEX versions, demonstrating depth in full-stack development.
