Developed the DeFi Portfolio Tab within the ava-labs/core-extension repository, enabling users to view, sort, and filter decentralized finance assets directly in the portfolio section. This work involved building interactive UI components in React, with a focus on protocol display cards and dynamic sorting and filtering controls. Leveraging JavaScript and TypeScript, the implementation enhanced asset management workflows by supporting richer user interaction and laying the groundwork for scalable DeFi analytics. The feature aligned with the next-generation portfolio strategy, providing a foundation for future enhancements while improving the overall user experience for managing DeFi assets within the application’s core extension.
