Joon Han | Digital Diagnostics

Clinical to Digital Analyst

Data and performance analyst applying diagnostic rigor to measurement, analytics, and decision support.

With a background in regulated clinical environments, I bring structured discipline to analytical problem-solving.

I approach analytics through hypothesis-driven testing, constraint diagnosis, and controlled experimentation.

I design measurement systems, transform data into structured insight, and support iterative decision-making at scale.
