About

Building AI systems that scale from zero to millions.

I'm a founding engineer with a track record of shipping AI products from 0→1 and scaling them to production. I've built systems that grew startups from $300K to $5M+ ARR, handling millions of workflow executions monthly.

My expertise spans LLM systems, agentic RAG, workflow orchestration, and production ML infrastructure. I've built AI teams and products at YC-backed startups and companies like Linqto and Simplr.ai (acquired). Master's in EECS from UC Berkeley, B.S. Data Science from UC San Diego.
