Healthcare Analytics & Data Engineering

About Me

I care deeply about the distinction between products and services as it pertains to the healthcare analytic space and optimizing the experiences of all users. I am always interested in discussions around population health analytics and related opportunities, especially in the health technology/digital health space.
