A federated health-data platform needed a researcher-facing portal — the surface where clinicians and analysts search hospital data, define patient cohorts, and run statistical studies, without any patient-level data ever leaving its source. A product spec and a partial workingprototype already existed. What didn't exist: a design that was trustworthy, coherent, and buildable on the company's design system.

The prototype worked, but it broke the platform's most important rule — internal technical routing language was leaking onto screens researchers would see. And the design system itself had never been asked to speak this language before: it was built for patients and caregivers, not for a data scientist deciding whether to trust a statistical result they didn't compute themselves. I owned both sides of the fix: the screen-level design, and the system it would live in.
