Before applying analytics to external systems, I built my own transition as a measurable digital system combining portfolio experiments,
GA4 measurement, case-study development, and AI-supported workflow design.
The Pivot Protocol documents the diagnostic thinking, experimentation, and iteration that shaped my move from clinical systems to digital growth.
