About

Building practical AI that works in the real world

With 15+ years spanning search, mobile, SaaS, and applied AI - and over a decade at Microsoft - I've built AI systems that serve hundreds of millions of users and led the teams behind them.

Today, as Chief of AI at Dewly AI, I'm building an AI Employee for Business Operation Automation. My work sits at the intersection of rigorous machine learning and real-world product impact: from pioneering ChatGPT's integration into Bing's ranking engine, to scaling recommender systems used org-wide, to turning AI into measurable operational outcomes for businesses.
