Rashmi Kanaveen developed portfolio explainability capabilities for the Intelligent-Advisor-Sem-4 repository, focusing on both backend and frontend enhancements. She implemented a FastAPI-based Portfolio Explainability API that leverages SHAP analysis and integrates with the Gemini API to generate human-readable explanations of portfolio performance, addressing transparency in risk and return. On the frontend, she built a React and TypeScript feature to fetch and display these explanations, incorporating robust UI states and animated loading. Her work included refactoring for type safety, explicit error handling, and comprehensive unit testing with pytest, resulting in maintainable, scalable analytics and improved user trust in financial insights.
