- State Management: React hooks (useState, useContext)
- Routing: React Router v6 for SPA navigation
- Styling: Tailwind CSS + CSS modules
- Component Library: Shadcn UI (Radix UI primitives)
Problem: Building a comprehensive financial dashboard with 40+ UI components initially resulted in 280KB+ gzipped bundle size, impacting initial page load.
Solution:
- ✅ Implemented code splitting and lazy loading for route-based pages
- ✅ Removed unused CSS utilities with Tailwind's tree-shaking
- ✅ Replaced chart libraries with optimized
recharts(38KB gzipped vs 80KB+ alternatives) - ✅ Used dynamic imports for heavy components used below the fold
- ✅ Minified and optimized all SVG icons
Result:
Before: 280KB
After: 120KB
Reduction: ~57% ✓
Problem: Cumulative Layout Shift score was 0.25, causing visual instability during data loads. Sidebar expansion, image loading, and skeleton states caused layout thrashing.
Solution:
- ✅ Reserved fixed space for all dynamic content with aspect-ratio containers
- ✅ Pre-allocated dimensions for charts and tables before data loads
- ✅ Used skeleton loaders with exact dimensions matching final content
- ✅ Applied
content-visibility: autoto off-screen content - ✅ Implemented font-display: swap to prevent font-related layout shifts
Result:
Before: CLS 0.25
After: CLS 0.08
Target: <0.1 ✓
Problem: The dashboard needed to work seamlessly from 320px mobile to 4K displays. Complex grid layouts caused overflow issues on tablets. Sidebar vs hamburger menu logic became convoluted.
Solution:
- ✅ Custom
use-mobilehook for responsive breakpoint detection - ✅ Tailwind's responsive classes (sm:, md:, lg:) for layout adaptation
- ✅ Collapsible sidebar with smooth transitions
- ✅ Mobile-first component design approach
- ✅ Tested across 15+ device breakpoints
Result: 100% responsive coverage with zero layout breaks. Native mobile experience.
Problem: Initial build lacked proper ARIA labels, color contrast issues, and keyboard navigation. Financial data accessibility is critical.
Solution:
- ✅ Integrated Radix UI primitives with built-in a11y features
- ✅ Added ARIA labels to all interactive elements
- ✅ Ensured 7:1 color contrast ratio for text
- ✅ Implemented keyboard navigation (Tab, Enter, Escape)
- ✅ Added skip-to-main-content link
- ✅ Used semantic HTML (proper heading hierarchy, alt text)
Result: WCAG 2.1 AA compliance. 100% accessibility audit pass.
Problem: Multiple dashboard views needed to respond to time-range changes (This Month, Last Month, This Year). State synchronization across components caused data inconsistencies.
Solution:
- ✅ Centralized time-range state in parent
Index.tsxcomponent - ✅ Passed callbacks down to child components
- ✅ Implemented proper prop drilling with React.memo to prevent re-renders
- ✅ Used local state for UI interactivity only
Result: Consistent data across all views. Single source of truth for time ranges.
