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.
Metric 140% Faster Dev
Metric 230% Fewer QA Cycles
Metric 399% Adoption
The Friction Point
The Problem
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 high security and fast page rendering speed while solving drop-off interfaces.
Process & Exploration
Auditing & User 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.
Interface Audit Findings
Identified 8 duplicate modal containers that abandoned native focus structures.
Touch-targets on mobile checkouts were 28px, failing Nielsen touch criteria.
Inline field instructions were overly complex and caused validation error spikes.
The Solution
The Final Interactive 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.
