The Problem

Where it started.

Doctors, nurses, and clinical staff were relying on a messaging app that worked against them. Urgent code warnings got buried in cluttered inboxes. On-call schedules didn't sync. New staff couldn't figure it out — so they gave up, fell back on slower methods, and gaps opened in patient care.

The consequences weren't just operational. Delayed consultations. Miscommunicated critical alerts. Coordinated care that broke down exactly when it mattered most.

"The problem wasn't that clinical staff didn't want to communicate well. The tool they were given made it nearly impossible."
Research

Listening before designing.

I embedded with the people using the app — shadowing nurses on rounds, sitting with doctors during shift changes, and interviewing staff about their most stressful communication moments. I built personas for doctors, nurses, and clinical staff, and mapped the full clinical messaging journey from alert to care delivery.

Process

From discovery to ship.

01

Discover & Research

Shadowing sessions, interviews with clinical staff, persona building, and full clinical messaging journey mapping.

02

Ideate & Wireframe

Low-fidelity explorations focused on message prioritization, intuitive navigation, and role-based communication flows.

03

Prototype & Test

Interactive prototypes for 1:1 and group clinical conversation flows, tested with clinical users in context.

04

Build & Ship

WCAG and HIPAA-compliant high-fidelity designs with full engineering and QA partnership.

Personas

The people behind the work.

Solution

What we built.

The new app was built around one principle: urgent things need to feel urgent. Color-coded message tags made code warnings impossible to miss. A redesigned bottom navigation matched the way clinical staff actually move - fast, often one-handed, mid-task. Better EHR and on-call scheduling integration meant the app finally worked with clinical systems instead of alongside them.

Takeaway

High-stakes environments demand high-empathy design. When you understand the most stressful moment a person faces in their workday and design for that, everything else follows. The best UX doesn't just reduce friction. It removes the conditions that make failure likely.
