Build a reusable design system for shared mobile components

[Lakes41]

Difficulty: Advanced
Type: Architecture / UI

Background

As new features continue to be added, UI components have naturally evolved throughout the application. Without a formal design system, maintaining visual consistency and reusing components becomes increasingly difficult.

Creating a shared component library will improve consistency, accessibility, and long-term maintainability.

Problem

Similar interface components exist in multiple places with slight implementation differences, increasing maintenance costs and making future UI improvements more difficult.

Expected outcome

Create a reusable design system containing standardized components, spacing, typography, colors, interaction states, and documentation for future contributors.

Suggested implementation

1. Audit reusable UI patterns across the application.
2. Consolidate duplicate components into a shared component library.
3. Standardize typography, spacing, color usage, and interaction states.
4. Improve accessibility across shared components.
5. Document component usage and design conventions.
6. Refactor existing screens to consume the shared components.

Acceptance criteria

• Shared UI components replace duplicated implementations.
• Typography and spacing are standardized.
• Accessibility improvements are incorporated into reusable components.
• Documentation explains component usage.
• Existing screens continue functioning without visual regressions.
