Building production-grade AI platforms with 5+ years of experience in agentic systems, voice AI, and cloud-native architectures.

About Me

I started my career at 18 as CTO of my own AI startup, building RAG pipelines and agentic systems from scratch. Five years and four companies later, I now lead a team of 6 engineers at NexOne AI, architecting financial and conversational AI platforms. My stack spans LangChain, LangGraph, AWS, Azure, Snowflake, and Twilio — always focused on shipping AI that works in production, not just in notebooks.
