- AI agents + generative AI

I work on AI agents and generative AI at Meta, and I write down what I learn. Off the clock: travel vlogs, a lot of books, and a cat named Humi.
Now: generative AI at Meta.
These days I work on AI-generated content (AIGC) in Meta's New AI Bets group. Before that I was an Agent Captain, helping teams move from reviewing AI output to designing autonomous agents.

Notes from working with agents.
Claude Code edits my travel vlogs now.
For my last dozen-plus travel vlogs I never opened a video editor. The workflow, what I still do, and why the cuts keep getting more like me.
I Deleted the UI and Just Talked to the Agent
I rebuilt my YouTube publishing tool from a Flask web app into a conversation with an agent in the terminal. Once it wasn't boxed into my forms, it started doing things no screen of mine could.
I Shipped Three Projects in 48 Hours Using Claude Code
How I built a YouTube Manager, personal website, and Life in Weeks visualization in one weekend using Claude Code — 137 commits, zero lines of code written by hand.
100+ travel vlogs on YouTube.
1,479 weeks, indexed.

Shanghai → Cornell → New York.
I grew up in Shanghai and majored in computer science at Cornell. I've been at Meta since 2020 and live in New York with my wife. I speak Chinese, English and French.
Before moving to AI agents, I built the compute behind the next generation of Deltoid, Meta's A/B test evaluation tool, and before that, privacy-preserving systems using techniques like differential privacy.
Here I write about what working with AI agents has actually changed. Outside work I make vlogs on YouTube, read a lot, and live with Humi, a cat with her own Instagram following.
