   - React 18+ RefObject types require non-nullable type param for ref props
   - Fixed useScrollReveal to return `RefObject<T>` instead of `RefObject<T | null>`
   - data-visible attribute pattern works well for CSS transitions based on JS state
+
+### Iteration 8 — Task 9: Build Education, Projects, Contact sections
+- **Completed**: Task 9 - Build Education, Projects, Contact sections
+- **Files created**:
+  - `src/components/Education.tsx` - Education cards with gradient top border
+  - `src/components/Projects.tsx` - Project cards with gradient border hover effect
+  - `src/components/Contact.tsx` - Contact grid with Lucide icons
+- **Files modified**:
+  - `src/App.tsx` - Replaced placeholder sections with actual components
+- **Design decisions**:
+  - **Education**: 2-column grid with gradient top border (teal→coral), hover elevation effect
+  - **Projects**: 2x2 grid with gradient border hover effect using CSS mask technique
+  - **Contact**: 4-column grid (2x2 on mobile), Lucide icons (Phone, Mail, Linkedin, MapPin)
+  - Framer Motion for staggered entry animations (100ms delay per card)
+  - useScrollReveal hook for scroll-triggered visibility
+  - ExternalLink icon from Lucide for project links
+  - Contact links use teal color with hover transition
+- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
+- **Learnings**:
+  - CSS gradient border hover effect uses mask-composite: exclude technique
+  - Lucide icons are tree-shakable - import only what's needed
+  - Contact items with href conditionally render as anchor tags
+
+### Iteration 9 — Task 10: Build Footer component and main App.tsx
+- **Completed**: Task 10 - Build Footer component and main App.tsx
+- **Files created**:
+  - `src/components/Footer.tsx` - Footer with decorative ECG waveform SVG
+- **Files modified**:
+  - `src/App.tsx` - Added Footer import and component to content phase
+- **Design decisions**:
+  - ECG waveform SVG matches concept.html: 120x20 viewBox with PQRST pattern
+  - Framer Motion for scroll-triggered entrance (opacity 0→1, y 16→0)
+  - Teal stroke at 30% opacity for subtle branding
+  - Font-secondary for text-xs muted attribution
+  - Footer placed outside main element as per semantic HTML
+- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
+- **Learnings**:
+  - App.tsx already had three-phase orchestration working correctly
+  - Footer scroll animation uses whileInView with once:true and margin:'-50px'
+  
+### Iteration 10 — Task 11: Implement scroll animations and responsive design
+- **Completed**: Task 11 - Implement scroll animations and responsive design
+- **Files modified**:
+  - `tailwind.config.js` - Added custom 'xs' screen at 480px for mobile breakpoint
+  - `src/App.tsx` - Added responsive padding (px-5 xs:px-6 md:px-8)
+  - `src/components/FloatingNav.tsx` - Responsive width and font/padding on mobile
+  - `src/components/Hero.tsx` - Responsive section padding, vitals grid, title font size
+  - `src/components/Skills.tsx` - Responsive grid (2→3→auto-fit), gauge size, padding
+  - `src/components/Experience.tsx` - Responsive card padding, ECG decoration size
+  - `src/components/Education.tsx` - Responsive section padding
+  - `src/components/Projects.tsx` - Responsive grid (1 col at tablet, 2 cols at desktop)
+  - `src/components/Contact.tsx` - Responsive section padding
+  - `src/components/Footer.tsx` - Responsive padding
+- **Design decisions**:
+  - Added 'xs' breakpoint at 480px to match concept.html mobile breakpoint
+  - Scroll-reveal animations standardized to opacity 0→1, translateY 24px→0 across all sections
+  - Responsive patterns from concept.html:
+    - 768px (md): 2-col grids, smaller nav padding, vitals 2-col grid
+    - 480px (xs): 1-col grids, smaller fonts, smaller gauges (64px), reduced padding
+  - Main container uses px-5 xs:px-6 md:px-8 for responsive horizontal padding
+  - Section padding uses py-12 xs:py-16 md:py-20 for consistent vertical rhythm
+  - Skills grid: 2 cols mobile, 3 cols tablet, auto-fit desktop
+  - Hero vitals: stacked mobile, 2-col tablet, flex row desktop
+- **Quality checks**: `npm run typecheck` ✓, `npm run lint` ✓, `npm run build` ✓
+- **Learnings**:
+  - Tailwind custom screens allow precise breakpoint matching to design specs
+  - Using w-16 h-16 xs:w-20 xs:h-20 for SVG gauges maintains aspect ratio while scaling
+  - Grid-based responsive layouts more reliable than flex-wrap for consistent card sizing
+
+### Iteration 11 — Task 12: Final integration, testing, and polish
+- **Completed**: Task 12 - Final integration, testing, and polish
+- **Quality checks verified**:
+  - `npm run typecheck` ✓ - No TypeScript errors
+  - `npm run lint` ✓ - No ESLint errors
+  - `npm run build` ✓ - Production build completes (290KB JS, 18KB CSS gzipped to 94KB/4.5KB)
+- **CV content accuracy verified** against CV_v4.md:
+  - Hero: Name, title, location, summary all match
+  - Experience: 5 roles in correct order with accurate dates and bullet points
+  - Education: MPharm UEA, Mary Seacole Programme with correct details
+  - Skills: 18 skills across Technical/Clinical/Strategic categories
+  - Projects: 4 projects with descriptions and PharMetrics link
+  - Contact: Phone, email, LinkedIn, location all accurate
+- **All 12 tasks completed** - React conversion finished
+- **Learnings**:
+  - Production build size is reasonable at ~94KB gzipped for JS
+  - All components properly typed with TypeScript strict mode
+  - IntersectionObserver hooks cleanup correctly on unmount
