What can a human-factors-focused UX designer do for you?
Refill approvals for dialysis clinics,
designed for speed, traceability, and patient oversight.
I cut in-clinic refill turnaround time by 70%, reduced phone follow-ups, and freed ~2 hours per nurse each week, all while improving patient oversight.
When I designed FreseniusRx’s first digital refill workflow end-to-end, dialysis-clinic teams approve refills in seconds, not minutes.
