Healthcare product leader with a deep AI/ML background.

I'm a data-focused technical product manager with deep experience in healthcare. I spent 6 years at Flatiron Health scaling infrastructure to extract facts about patients from health record documents, including shipping the first ML-extracted research datasets, now a 10M+ business. I've helped clients with everything from UX research and design to understanding product analytics to scoping new product opportunities and running market research.
