About
Who I am
I am a software engineer, with 6+ years building scalable platforms using Node.js, TypeScript, React, and AWS. Today my focus is AI Platform Engineering - combining production-grade architecture with Generative and Agentic AI to build intelligent, reliable systems at scale. Off the keyboard, I love jogging and exploring new places.
