About

Former GenAI Team Lead who shipped Agentic AI Systems, Advanced RAG, and the backend infrastructure behind a B2B platform serving CTBC Bank, MSI, HPE, and iGroup — work that contributed to the Presidential Hackathon Winner (2024) and 23rd Golden Peak Award (2025). I care about systems that survive contact with real users: retrieval that scales past 20M+ chunks, agents that don't burn tokens, and test coverage that catches regressions before they ship.

Now at Rice (GPA 4.00) and joining Google as a SWE intern.

Featured Work

🧠 Agentic Hybrid RAG

LangGraph · Neo4j · Milvus · Multi-Agent

Self-routing agentic system that picks Graph RAG, Vector RAG, or a hybrid path per query. Achieved 88.2% MAR@10 on multi-hop datasets and cut indexing token cost by 35% via ML-clustered pivotal node selection.

🎓 Multi-Agent Tutoring RAG

CrewAI · LangChain · Streamlit · Chroma

Multi-agent tutoring system with role-specialized LLMs for problem-solving, exam detection, and concept analysis. Top 3 of 50 teams at the NYCU CS AI workshop (Outstanding Award).

🦙 LlamaIndex Contributions

Open Source · 15K+ ⭐

14 merged PRs across AWS Bedrock, Claude, Elasticsearch, Cohere, OpenAI, MCP Client, and the AI Agent Workflow modules — bug fixes, new integrations, and capability extensions.

🚀 MaiAgent Production Platform

Django · FastAPI · LlamaIndex · AWS

Led GenAI roadmap for a 10-person startup. Upgraded chatbots into AI agents with memory + tools + MCP, driving 120% partner growth and 67%+ token reduction. Introduced pytest framework reaching 67% coverage from zero.
