Notes from the work
On AI, technology, and what comes next.
The Great AI Divergence
The AI divide runs from models and agents to what people can reliably do. Small, reusable skills can multiply when they make one another more useful.
Founders Club at the 2026 HYSTA Annual Conference
This year, I was delighted to co-host the Founders Club track at the HYSTA Annual Conference with Nikita, bringing together founders, investors, and friends both old and new.
In the AI Era, the Boundary of Expertise Has Blurred
A family member had a nosebleed that wouldn't stop for two hours. Every consumer AI told me to go to the ER and refused to say anything useful. Then I changed the question — and got the actual protocol.
Guides & hobbies
Practical, well-sourced guides from life in the Bay Area.
- Bay Area shore fishing
36 coastal areas, 44 species, an interactive map, tackle and casting lessons.
In Chinese - Bay Area home buying
Nine cities, five-year prices, home styles, risks, mortgages and a first-home guide.

Waterfront views, stroller routes, parking areas, restrooms and map links.
In Chinese
From infrastructure to people.
My work spans the systems behind products, the products people use, and the teams and communities that build them.
Always learning. Always sharing.
Studies in AI at Stanford and a master’s in Computer Engineering from NYU. Along the way, mentoring engineers and sharing what I learn.
