Technical explorations solving specific friction points in design systems and AI interfaces.

Design System Handoff Patterns

9 specification dimensions

Component specification architecture I developed at MinoHealth to reduce design-dev friction. Includes state management matrix, token naming conventions, and accessibility annotations.

View Patterns

Specification Dimensions

  • Exhaustive state management (Loading, Empty, Errors)
  • Strict token and naming adherence (PascalCase, Semantic tokens)
  • WCAG 2.1 AA+ contrast and navigation compliance
  • Semantic and keyboard navigation (ARIA, tab orders)
  • Responsive behaviors and fluid breakpoints defined
