UI & UX — Design System
Principles, components, and patterns I use to design and build delightful, accessible, and performant user experiences.
Clarity
Interfaces that communicate purpose and hierarchy.
Consistency
Reusable components and predictable interactions.
Readability
Readable typography and comfortable line-lengths.
Delight
Micro-interactions that make the product feel alive.
Design Tokens
Primary Colors
Use primary for CTAs, accents, and highlights.
Typography
Inter / system UI
H1: 36–48px
H2: 24–30px
Body: 16px, line-height 1.6
Spacing Scale
4 / 8 / 12 / 16 / 24 / 32 — use consistent spacing tokens.
Radius & Elevation
Border radius: 8px (cards), 12px (dialogs). Soft shadows for elevation.
Accessibility & Performance
- Contrast ratios meet WCAG AA for body text.
- Semantic HTML and keyboard navigation for all components.
- Images optimized (responsive sizes + lazy loading).
- Critical CSS inline, defer non-critical styles — keep LCP low.

Card Title
Brief description of the card content and why it's useful.
Responsive Patterns
Desktop Navigation
Use top nav with clear grouping, search, and account actions. Keep CTAs visible.
Mobile Patterns
Use bottom navigation for primary actions, minimize modal frequency, and ensure large tappable targets.

- Measure with analytics and user feedback.
