What I'm looking for

I'm looking to build and improve production conversational AI systems, partnering with clients and cross-functional teams to deliver reliable agent experiences and measurable outcomes.

At PolyAI, I own production voice agents across enterprise insurance, healthcare, residential property, logistics, and banking clients. I led a 15-site residential deployment that exceeded go-live targets with 36% containment and 58% tour booking, and improved healthcare-agent containment from 42% to 48.5%.

I've also led generative AI delivery at Amazon, translating ambiguous model requirements into structured workflows, prompt evaluations, QA standards, and capacity forecasts. My work combines conversational AI design, client onboarding, production reliability, and cross-functional delivery.
