01 / Challenge

Every Screen Looked and Behaved a Little Differently

The client's internal scheduling application was built on jQuery and page-by-page templates a decade earlier, with every screen looking and behaving slightly differently, making staff onboarding slow and small changes disproportionately time-consuming.

02 / Approach

A Reusable Design System, Then a Screen-by-Screen Rebuild

We built a reusable component-based design system in React, then rebuilt the application screen by screen against it, starting with the highest-traffic scheduling workflows, while keeping the underlying data layer stable throughout.

03 / Architecture

From Inconsistent Templates to a Shared Component Library

The underlying data layer stayed stable throughout, so the interface modernized without touching what already worked underneath it.
