Summary
I redesigned FreseniusRx’s medication refill workflow, from data model to UX, so busy dialysis‑clinic teams can approve refills in seconds instead of minutes. The new flow cut turnaround time 70 %, eliminated the need for phone follow‑ups, and freed nurses ≈2 hrs per week. All this while enhancing patient oversight.

Mapped a complex workflow

Translated dozens of scattered data points into a handful of clinician-friendly objects that matched the pharmacy’s data model.

Maps to wireframes to prototypes to refills

Converted the object map into wireframes and clickable prototypes, iterating with nurses until a one-click refill screen cut refill time by 70 %.

Piloted, de-risked, and scaled

Ran a two-week pilot, fixed edge cases, then rolled the workflow to 2,800+ clinics, freeing nurses ~2 hrs/week.

Summary
I worked closely with a practicing physician frustrated by the inefficiencies and cognitive burden of current EHRs. The second-generation EHR that I helped create with him replaces tabbed, source-oriented data structures with problem-oriented timelines for efficient and effective chart review.

Aligning with clinician mental models

Interviewed physicians and analyzed real-world artifacts to map cognitive workflows and problem-oriented thinking, ensuring product requirements matched how clinicians diagnose and manage patient issues.

Aligning with clinician mental models

Enabled rapid identification of patterns and anomalies

Designed an integrated patient timeline that visualizes labs, vitals, diagnoses, and medications side-by-side, making it easy for clinicians to spot trends and outliers in seconds.

Summary
When Medicaid let Dell Children's know that they needed to add functionality to their patient portal to stay in compliance with new standards, they went to Ascension Health for a solution. Ascension got in touch with me to lead the small but mighty team, working in a tight timeline with limited resources.

Critical functionality that members need

Transformed a generic, underpowered portal into a Medicaid-compliant tool that delivers essential features for parents managing their children’s care—aligning teams to prioritize what members actually need.

Prototype to production

Used multi-fidelity prototypes to test ideas with stakeholders and uncover technical shortcuts—repurposing existing APIs to enable new dependent-care features without overhauling infrastructure.

Mobile-first with meaning

Redesigned the portal for mobile-first use by parents juggling complex care—delivering a clean, personalized dashboard that surfaces ID cards, care teams, and key tasks upfront.
