About Me

I build production AI platforms. As the first engineer at an AI startup, I designed and shipped the entire technical foundation — from Azure cloud infrastructure to LangGraph multi-agent systems to a Next.js frontend with real-time AI streaming. 4+ years across backend engineering, AI/ML systems, and cloud-native deployment.
