I'm a Solution Architect at Tencent Americas, where I design and deploy CDN and cloud infrastructure for enterprise clients. I work at the intersection of enterprise infrastructure and AI — specifically, what it takes to architect AI into production systems that have real latency budgets, real compliance constraints, and real consequences when they fail.

I write publicly about what I learn — eval frameworks, deployment patterns, and the gap between Claude demos and Claude in production.
