The Challenge

The .NET-based Customer Portal was built by third-party developers with no design system foundation.

As new features and pages were added, the lack of scalability and flexibility became critical. Components were completely fragmented with no connection points, making maintenance and expansion nearly impossible.

The Solution

I created a comprehensive design system that unified component styles and established centralized controls.

This included component libraries, patterns, page templates, and comprehensive documentation to accelerate development and improve collaboration between designers and developers.

Sketches and initial notes

Initial system audit and research

Old interface and inconsistencies

Fragmented component analysis

Component Unification

I unified 50+ fragmented components into a cohesive design system.

Standardized tokens, patterns, and reusable elements that eliminated visual inconsistencies and enabled rapid development.

Centralized Control

I established a centralized design control system for easy maintenance.

Design tokens, component libraries, and pattern libraries that developers could easily implement and customize.

UI components and tokens

Unified component library and design tokens

Template System

I created scalable page templates that accelerated new feature development.

Consistent layouts and patterns that developers could quickly implement and customize.

Developer Collaboration

I established clear communication channels between design and development teams.

Comprehensive documentation and resource pages that improved workflow efficiency and reduced development time.

Responsive modal UI

Template library and patterns

Grid layout and collapse states

Developer collaboration workflow

Design Guides & Resources

I created comprehensive design guides and resource pages as a single source of truth.

For both designers and developers, improving workflow efficiency and reducing communication overhead.

Workflow Optimization

I established clear processes and communication channels for seamless collaboration.

Between design and development teams, resulting in faster iteration cycles and improved product quality.

System documentation

Comprehensive design guides and resources

Development Acceleration

The design system reduced development time by 40% for new features.

While maintaining visual consistency and quality across all components and pages.

Scalable Foundation

The unified system provided a solid foundation for future growth.

Enabling rapid expansion of features while maintaining design consistency and reducing maintenance overhead.
