Designing Alignment: A Scalable Web Design System for MNTN

I was the leading designer of MNTN's comprehensive web design system for responsive web and mobile platforms. Established design foundations, crafted reusable components with design guidelines with corresponding design tokens in Figma. I collaborated closely with the engineering team and introduced accessibility documentation to ensure a consistent, inclusive user experience across all touch-points.

As a result, the new system reduced maintenance overhead by 50%, enabled rapid brand setup, and streamlined the design-to-development handoff.

Inconsistent UI: Designers and Developers Out of Sync

Inconsistent UI: Designers and Developers Out of Sync

01

When I joined the design team, I found there was no shared design system or visual source of truth. As a result, brand designers frequently made inconsistent changes to UI elements like buttons, cards, and accordions, forcing developers to rebuild components from scratch and creating misalignment across the product.

In addition, inconsistent design language generated numerous QA tickets from sales and operations teams, undermining brand credibility and creating internal friction.

Implementation Goals

02

Establish a unified design system to eliminate design duplication, standardize visual language across all platforms, implement consistent naming conventions, and streamline design-to-development handoffs.

Success metrics:

  • Reduce QA tickets by 90% and

  • Achieve 90% visual consistency across product interfaces

  • 50% reduction in dev team maintenance

Research That Shaped the Foundation

03

I started with a comprehensive audit of existing design patterns, deconstructing live pages into individual UI components to understand current usage. Partnering with a front-end developer, we extracted and cataloged all UI variables to ensure technical alignment. We took an iterative approach, systematically reviewing and documenting each component to build a solid foundation for the design system. Here are some legacy components.

Creating the Token System

04

I structured our design tokens using Style Dictionary conventions, implementing clear names and semantic alias layers for consistency. Using MNTN's main colors as visual examples:

Here’s an overview of the improvements I made: I refined the color palette to ensure accessibility compliance, created a reusable template for brand designers to easily drag and drop design inspiration, updated the card system for better consistency, and restructured the button components for clearer hierarchy and easier implementation.

Handoff documentation typically begins with an overview of the design token system, followed by a comprehensive documentation sheet covering component specs, usage guidelines, and developer notes.
