Incoming Computer Engineering student at Washington University in St. Louis. I build AI systems, agent safety evals, RAG pipelines, and reliability infrastructure for tool-using AI.

Daily Admin Agent Security Eval — AgentDojo-compatible eval suite for tool-using daily-admin agents. 5 user tasks, 8 injection tasks, synthetic tools, preflight checks, and OpenAI-compatible model runners. Tests whether agents can complete useful tasks while treating retrieved app content as untrusted data.

LawAI — Privacy-aware RAG legal assistant. Enforces document-level access via Auth0 FGA (HR sees salary docs, engineers denied). RAG pipeline with Pinecone + multilingual-e5-large embeddings. Includes AI evaluation framework using DeepSeek judge to score responses on safety, specificity, and actionability. Next.js 15 + DeepSeek V4 Pro.

Lesson Plan Generator — RAG system for 95K+ curriculum chunks. ChromaDB + Qwen LLM. End-to-end pipeline with OCR error correction and semantic search. Deployed in rural Guizhou schools.

StatsifyFinance — AI financial analysis. DeepSeek V3 streaming, LangChain orchestration, dual OCR (Tencent + Baidu) for document understanding.

BiphFlora — Plant encyclopedia with image recognition. Built a searchable database of plant species with identification features.
