Overview

How we aligned a team of 45 engineers and designers on a single source of truth, eliminating design debt and accelerating shipping velocity.

A scalable component language for repeated flows, consistent decisions, and faster handoff.

Result 140% Faster Dev

Result 230% Fewer QA Cycles

Result 399% Adoption

Problem

The friction point

Designers were inventing custom components for every page, resulting in hundreds of button variants and a fragmented user experience. Handoffs were slow and error-prone, taking days of manual visual QA.

Core constraint

Maintain security and rendering speed while eliminating drop-off points.

Process

Auditing & prototyping

We audited 200+ screens and identified redundancies. Next, we drafted visual tokens for spacing, typography, and color, and prototyped responsive component patterns. We ran usability testing sessions to verify touch targets and contrast ratios.

Audit findings

8 duplicate modal containers abandoned native focus structure.
Mobile touch targets at 28 px — below the 44 px Nielsen threshold.
Inline validation fired only on submit, causing error-rate spikes.

Solution

The final UI

A tokenized design system built in Figma and mirrored in code via React/CSS, complete with interactive playgrounds, comprehensive dark mode, and rigid accessibility specs.

Before — audited wireframe

After — production UI
