Generative AI
- Built an AI-agent chatbot for financial advisors to automate client data retrieval, transaction orders, and account actions, streamlining complex advisory workflows.
- Implemented progressive MCP tool discovery with a “Code Mode” pattern so agents load tool schemas via code execution—cutting context bloat by ~90% and improving token efficiency.
- Architected and migrated the internal AI stack to the Model Context Protocol (MCP) using Pydantic AI for type-safe agents that orchestrate multi-step work across unified data sources.
- Rebuilt the chatbot UI by forking and customizing the Vercel AI SDK with Next.js, with strong client-side state management.
- Added response streaming for lower perceived latency and higher engagement via word-by-word output.
- Connected heterogeneous knowledge bases with LangChain and Unstructured.io through MCP for reliable retrieval across teams.
- Ran DeepEval-based evaluations so agent flows, code execution, and outputs meet financial-industry quality bars.
Machine learning
- Led an automated ML system for credit risk and trading-limit decisions, improving operational efficiency.
- Benchmarked 10+ models (SVM, neural nets, XGBoost, etc.) on imbalanced binary classification with unbiased confusion-matrix analysis.
- Shipped XGBoost with ~90% automation coverage and >98% accuracy, keeping Type I errors strictly low while cutting manual work.
