Summary: I am a cloud and developer platform leader with 25+ years of experience spanning product management, product marketing, and hands-on software development. I’ve helped launch and scale infrastructure products including Kubernetes, object storage, DNS, and CDN services, and currently lead product for a 1M+ user multi-sided marketplace platform.

I remain deeply hands-on with modern development workflows, building AI-native web applications using Next.js and Vercel, integrating LLM-based capabilities, and experimenting with developer tooling that accelerates product velocity. I’m particularly interested in how AI-native infrastructure and modern frontend platforms are reshaping how developers ship.
