Cloud Architect & AI Engineer. Building scalable systems on cloud.

AI/ Cloud Native Engineer passionate about the intersection of cloud and Modern AI. I focus on the hard parts of engineering: cost optimization, security at scale, and the architectural patterns required to move Generative AI from a messy notebook to a production-grade system. I write to document what actually works in production.
