Projects
Eight things I put the most care into. Open a card for the full product and engineering story.
AI Products
Turning AI capability into usable products.
NL2SQL Reporting Agent
Just say "average math score last term" and get a chart in seconds — a new interaction paradigm from GUI to LUI.
RAG Knowledge-Base QA
Ask "what is an LLM hallucination" and get an answer with page-level citations in seconds; asked something beyond the material, it says so instead of making it up.
Education OR Optimization Toolkit
Mathematical modeling automatically solves course scheduling and class assignment — minutes instead of weeks of manual work.
Content & Education
Explaining the abstract, animating the heritage.
AI Literacy Course
A 30,000-word lecture series plus field-study handbook that gives non-technical people a real framework for thinking about AI.
Mingkeming
A 48-hour hackathon project that turns short videos into personalized language textbooks.
Heritage Architecture Study
Two study handbooks on traditional Chinese architecture for young readers, plus a set of Beijing Central Axis bookmarks — hand-drawn illustration turning "too complex to read" into something you can page through.
Games & Experiments
Trying methods where it's fun.
Xiaoshan Xunzong
An immersive puzzle game: through close reading, players discover the cracks between "what is told" and "what is true."
Lobster Simulator
An ABM simulation of survival-strategy evolution in a closed population — cooperation or competition? The answer is counterintuitive.
