Quse Design System

Consulting client · Quse · iOS & Web

Built a design system from scratch to make development faster and more consistent.

Quse's early screens weren't tied to any component library or shared system. I built one from scratch to unify the experience and support future versions.

The Problem

The product lacked a unified system, leading to inconsistencies, duplicated work, and slower development.

Without shared standards, it was difficult to scale efficiently.

My Role

LEAD PRODUCT DESIGNER
I built the system on my own, from primitives and semantic tokens to components, patterns, and documentation, while redesigning the app alongside it.

WHAT SHIPPED

  • Primitive and semantic color tokens with light and dark modes

  • Core components and patterns for mobile and web

  • Queue-specific colors and icons for Upcoming, Saved, and Everyday

  • Documentation to guide usage

Decisions & Trade-offs

NAMING TOKENS BY USAGE

I named semantic tokens by where they’re used, such as background/queue/upcoming/primary, so engineers could pick the right color without guessing and a theme change would only touch one layer.

BUILDING DARK MODE IN FROM THE START

Dark mode wasn’t in the app yet, but I gave every token light and dark values so the team could add it later without reworking the system.

Constraints

The system needed to support a small team and evolving product without introducing unnecessary complexity.

What Changed

Engineers built faster and came to me with fewer questions about how to use components. The product gained a consistent visual and interaction language, ready for dark mode when the team adds it.

Hindsight

Future improvements could include expanded documentation and deeper integration with engineering workflows.
