A faithful daughter of God, a loving wife, a cat mom, an amateur painter/doodler.
I love things that look effortless because someone cared about the details: software that never goes down, a painting that feels finished, a well-made Americano to start the morning. These days I teach AI agents to behave themselves. Mostly.
A decade in tech, from Meta to scrappy startups, taught me that the good stuff is elegant, a little stubborn, and made with care.
Originally from Beijing, now happily settled in Irvine, California. Wherever life takes me, my foundation will always be in God.
AI & Agentic Systems
I build the systems that make AI agents dependable enough for real work: rules enforced in code rather than politely requested in prompts, evals that tell whether an agent is doing its job or just sounding confident, and a second agent that audits the first. At Linktree, an agent I built tests every pull request, and moving its rules from prompts into code made it cheaper and far more reliable. Now I'm building a self-healing system that catches production issues, has a coding agent fix them, and decides whether each fix is safe to ship. Its best feature is knowing when not to trust itself.
Languages & Frameworks
I build across the whole stack, from a React front end to a GraphQL API to a SQL query that really should have had an index, and I obsess over one thing: how it all feels to the person on the other end.
Full-Stack, Pipeline to Pixels
End to end is where I do my best work. I've shipped everything from the CI/CD pipeline and DevOps underneath, through cloud and edge infrastructure, up to the front-end experience and the A/B test that tells you whether it worked. When something breaks, I follow it to wherever it actually lives, and I'd much rather fix the root cause than keep being the person who gets paged.
I build agentic AI solutions and AI-powered products. Let's create something meaningful together.
