DESIGN SYSTEM
Project Summary
The brief was to make CAIR usable, but the real rot was that CDPH had no design system at all, so I built one.
CAIRHub is the front door to California's immunisation registry, used by clinics, schools, and parents who share nothing except the same screen.
Before
A legacy template stretched across mismatched apps, dense, inconsistent, and hostile to anyone on assistive technology.
Final Experience
One sorted hub with a task flow that behaves the same every time, responsive across every width, finally clearing the accessibility bar it was legally required to meet.
The Outcome
The redesign drove a 346% increase in user sessions, measured against the pre-508 baseline in Google Analytics and CDPH records.
I owned the version that shipped across 2022 to 2023, and I claim that work and its outcome, not whatever sits on the server today.
