Build something people want.

( Hello )

I'm a founding AI engineer and de facto PM at ( LlamaIndex ), where I build document-processing AI infrastructure for Fortune 500 companies and high-growth startups. My work spans forward-deployed engineering, product engineering, and product management.

Before that: solutions engineering at Enigma and Sisu, and consulting at Deloitte. Outside work I love karaoke, ( Go ), the Chinese strategy board game, the piano, and trying creative ideas with the latest AI tools.
