+### Current State
+
+| Category | Status | Score |
+|----------|--------|-------|
+| SEO | ✅ Complete | 100% |
+| Accessibility | ✅ Passing | 92-100% |
+| Best Practices | ✅ Passing | 100% |
+| Performance (Dev) | ⚠️ Expected Low | 47-69%* |
+| Performance (Prod) | 📋 To Verify | Expected 85-95% |
+
+*Development mode scores are lower due to unminified code, HMR overhead, and source maps.
+
+---
+
+## Priority 1: Critical Optimizations (Immediate Action)
+
+### 1.1 Image Optimization - Hero Portrait
+
+**Issue:** The hero portrait image is 2.9 MB, significantly impacting LCP and overall page weight.
+
+**File:** `/public/hero-portrait.jpg`
+**Current Size:** 2,957,516 bytes (~2.9 MB)
+**Target Size:** < 500 KB (80-85% reduction)
+
+**Recommendations:**
+```bash
+# Option 1: Manual compression with ImageMagick
+magick hero-portrait.jpg -quality 82 -strip hero-portrait-optimized.jpg
+
+# Option 2: Convert to WebP format
+magick hero-portrait.jpg -quality 80 hero-portrait.webp
+
+# Option 3: Use AVIF for maximum compression
+magick hero-portrait.jpg -quality 60 hero-portrait.avif
+```
+
+**Implementation Steps:**
+1. Compress original to <500KB maintaining visual quality
+2. Generate responsive variants (300, 600, 900, 1200px widths)
+3. Create AVIF and WebP versions for modern browser support
+4. Update Next.js Image component with blur placeholder
+5. Add `fetchpriority="high"` for LCP optimization
+
+**Expected Improvement:**
+- LCP: -1.5 to 2.0 seconds
+- Page weight: -2.0 to 2.5 MB
+- Mobile performance: +15-25 points
+
+---
+
+### 1.2 Unused Large Images Cleanup
+
+**Issue:** Multiple large image files may not be referenced in production.
+
+**Files to Audit:**
+| File | Size | Status |
+|------|------|--------|
+| `/public/portrait.jpg` | 1.2 MB | Verify usage |
+| `/public/hero-portrait.jpg` | 2.9 MB | Needs optimization |
+
+**Recommendation:**
+1. Run image usage audit:
+   ```bash
+   grep -r "portrait.jpg" src/ --include="*.tsx" --include="*.ts"
+   grep -r "hero-portrait.jpg" src/ --include="*.tsx" --include="*.ts"
+   ```
+2. Replace references with optimized versions
+3. Remove unused originals from `/public`
+
+---
+
+### 1.3 Production Performance Verification
+
+**Issue:** PageSpeed API was blocked during testing. Production verification required.
+
+**Action Required:**
+1. Visit [PageSpeed Insights](https://pagespeed.web.dev/)
+2. Test all main URLs:
+   - `https://www.damjan-savic.com/de`
+   - `https://www.damjan-savic.com/en`
+   - `https://www.damjan-savic.com/sr`
+   - `https://www.damjan-savic.com/de/about`
+   - `https://www.damjan-savic.com/de/portfolio`
+   - `https://www.damjan-savic.com/de/contact`
+
+3. Document scores for Desktop and Mobile
+4. If any score < 90%, implement specific recommendations from report
+
+---
+
+## Priority 2: High-Impact Optimizations (This Sprint)
+
+### 2.1 Client Component Audit
+
+**Issue:** 13 client-side components identified. Some may be convertible to React Server Components (RSC).
+
+**Current Client Components:**
+
+| Component | Client Necessary? | Recommendation |
+|-----------|-------------------|----------------|
+| Header.tsx | ✅ Yes | Scroll/menu state |
+| ContactForm.tsx | ✅ Yes | Form state |
+| LoginForm.tsx | ✅ Yes | Form state |
+| PortfolioCard.tsx | 🔍 Review | Consider RSC |
+| PortfolioGrid.tsx | 🔍 Review | Consider RSC |
+| NavLink.tsx | 🔍 Review | Consider RSC |
+| ContactInfo.tsx | 🔍 Review | Consider RSC |
+| Skills.tsx | 🔍 Review | Animation-dependent |
+| Experience.tsx | 🔍 Review | Animation-dependent |
+| Hero.tsx (about) | 🔍 Review | Animation-dependent |
+| LanguageSwitcher.tsx | ✅ Yes | Dropdown state |
+| DashboardContent.tsx | ✅ Yes | Auth state |
+| Chatbot.tsx | ✅ Yes | Interactive |
+
+**Recommendation:**
+1. For animation-dependent components, consider:
+   - Static initial render as RSC
+   - Minimal client wrapper for animations only
+   - Use CSS animations where possible (GPU-accelerated)
+
+2. Conversion pattern:
+   ```tsx
+   // Before: Full client component
+   'use client';
+   export function PortfolioCard({ project }) {
+     return <div>{/* all content */}</div>;
+   }
+
+   // After: Server component with client wrapper
+   export function PortfolioCard({ project }) {
+     return (
+       <PortfolioCardWrapper>
+         <div>{/* static content */}</div>
+       </PortfolioCardWrapper>
+     );
+   }
+   ```
+
+**Expected Improvement:**
+- JavaScript bundle: -50-150 KB
+- TTI (Time to Interactive): -200-500ms
+
+---
+
+### 2.2 Loading States and Suspense Boundaries
+
+**Issue:** No loading.tsx files detected for route segments.
+
+**Recommendation:**
+Create loading states for improved perceived performance:
+
+```tsx
+// src/app/[locale]/loading.tsx
+export default function Loading() {
+  return (
+    <div className="animate-pulse">
+      <div className="h-8 bg-gray-200 rounded w-1/3 mb-4" />
+      <div className="h-4 bg-gray-200 rounded w-full mb-2" />
+      <div className="h-4 bg-gray-200 rounded w-2/3" />
+    </div>
+  );
+}
+
+// src/app/[locale]/portfolio/loading.tsx
+export default function PortfolioLoading() {
+  return (
+    <div className="grid grid-cols-1 md:grid-cols-2 gap-6">
+      {[...Array(6)].map((_, i) => (
+        <div key={i} className="animate-pulse rounded-lg bg-gray-200 h-64" />
+      ))}
+    </div>
+  );
+}
+```
+
+**Files to Create:**
+- `src/app/[locale]/loading.tsx`
+- `src/app/[locale]/about/loading.tsx`
+- `src/app/[locale]/portfolio/loading.tsx`
+- `src/app/[locale]/contact/loading.tsx`
+
+---
+
+### 2.3 Blur Placeholder for Hero Image
+
+**Recommendation:**
+Add blur placeholder for improved perceived LCP:
+
+```tsx
+// In Hero component
+import Image from 'next/image';
+
+// Generate blur data URL (base64 encoded tiny version)
+const heroBlurDataURL = "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQ..."; // Generate with plaiceholder
+
+<Image
+  src="/hero-portrait.jpg"
+  alt="Damjan Savić"
+  fill
+  priority
+  placeholder="blur"
+  blurDataURL={heroBlurDataURL}
+  sizes="(max-width: 768px) 100vw, 50vw"
+/>
+```
+
+**Implementation:**
+1. Install plaiceholder: `pnpm add plaiceholder sharp`
+2. Generate blur data URLs at build time
+3. Update Image components with placeholder prop
+
+---
+
+## Priority 3: Medium-Impact Optimizations (Next Sprint)
+
+### 3.1 Reduced Motion Support
+
+**Issue:** Background SVG animations may cause issues for users with vestibular disorders.
+
+**File:** `/src/components/layout/GlobalBackground.tsx`
+
+**Recommendation:**
+```tsx
+// Add media query support
+const GlobalBackground = () => {
+  const prefersReducedMotion = useMediaQuery('(prefers-reduced-motion: reduce)');
+
+  if (prefersReducedMotion) {
+    return <StaticBackground />;
+  }
+
+  return <AnimatedBackground />;
+};
+
+// Or use CSS-only approach
+<style>
+  @media (prefers-reduced-motion: reduce) {
+    .animated-bg * {
+      animation: none !important;
+      transition: none !important;
+    }
+  }
+</style>
+```
+
+---
+
+### 3.2 Third-Party Script Optimization
+
+**Issue:** Google Analytics may block rendering if not loaded properly.
+
+**Current Implementation:** Review needed
+
+**Recommendations:**
+1. Use Partytown for off-main-thread execution:
+   ```bash
+   pnpm add @builder.io/partytown
+   ```
+
+2. Defer non-critical scripts:
+   ```tsx
+   // In layout.tsx or Script component
+   import Script from 'next/script';
+
+   <Script
+     src={`https://www.googletagmanager.com/gtag/js?id=${GA_TRACKING_ID}`}
+     strategy="afterInteractive"
+   />
+   ```
+
+3. Consider self-hosting analytics for better control:
+   - Plausible Analytics (privacy-focused, <1KB)
+   - Umami Analytics (self-hosted option)
+
+**Expected Improvement:**
+- TBT (Total Blocking Time): -50-100ms
+- FCP: -100-200ms
+
+---
+
+### 3.3 Font Loading Optimization
+
+**Current State:** ✅ Font swap implemented (good baseline)
+
+**Further Optimizations:**
+1. Subset fonts to required characters only:
+   ```css
+   /* Only load Latin subset */
+   @font-face {
+     font-family: 'Inter';
+     src: url('/fonts/inter-latin.woff2') format('woff2');
+     unicode-range: U+0000-00FF, U+0131, U+0152-0153;
+   }
+   ```
+
+2. Preload critical font files:
+   ```html
+   <link
+     rel="preload"
+     href="/fonts/inter-var.woff2"
+     as="font"
+     type="font/woff2"
+     crossorigin="anonymous"
+   />
+   ```
+
+3. Consider variable fonts to reduce total file count
+
+---
+
+### 3.4 Database Indexing for Chat
+
+**Issue:** Chat queries may become slow with scale.
+
+**Current Indexes:**
+- `idx_chat_messages_session` on `session_id`
+
+**Recommended Additional Indexes:**
+```sql
+-- For visitor lookup (session continuity)
+CREATE INDEX idx_chat_sessions_visitor
+ON chat_sessions(visitor_id);
+
+-- For recent sessions (cleanup queries)
+CREATE INDEX idx_chat_sessions_created
+ON chat_sessions(created_at DESC);
+
+-- For message ordering
+CREATE INDEX idx_chat_messages_created
+ON chat_messages(session_id, created_at);
+
+-- Composite index for efficient session + message retrieval
+CREATE INDEX idx_chat_messages_session_created
+ON chat_messages(session_id, created_at DESC);
+```
+
+---
+
+## Priority 4: Strategic Improvements (Backlog)
+
+### 4.1 Progressive Web App (PWA) Implementation
+
+**Benefit:** Offline support, app-like experience, improved mobile engagement
+
+**Implementation:**
+
+1. Create service worker:
+   ```typescript
+   // src/app/sw.ts
+   import { precacheAndRoute } from 'workbox-precaching';
+
+   precacheAndRoute(self.__WB_MANIFEST);
+   ```
+
+2. Add manifest:
+   ```json
+   // public/manifest.json
+   {
+     "name": "Damjan Savić - Portfolio",
+     "short_name": "DS Portfolio",
+     "start_url": "/",
+     "display": "standalone",
+     "background_color": "#0a0a0a",
+     "theme_color": "#3b82f6",
+     "icons": [
+       { "src": "/icon-192.png", "sizes": "192x192", "type": "image/png" },
+       { "src": "/icon-512.png", "sizes": "512x512", "type": "image/png" }
+     ]
+   }
+   ```
+
+3. Configure next.config.ts for PWA:
+   ```bash
+   pnpm add next-pwa
+   ```
+
+---
+
+### 4.2 Bundle Analysis and Code Splitting
+
+**Recommendation:**
+1. Analyze current bundle:
+   ```bash
+   pnpm add @next/bundle-analyzer
+
+   # In next.config.ts
+   const withBundleAnalyzer = require('@next/bundle-analyzer')({
+     enabled: process.env.ANALYZE === 'true',
+   });
+
+   module.exports = withBundleAnalyzer(nextConfig);
+
+   # Run analysis
+   ANALYZE=true npm run build
+   ```
+
+2. Identify large dependencies for lazy loading:
+   - framer-motion (if not needed on all pages)
+   - lucide-react icons (ensure tree-shaking)
+   - openai SDK (server-only)
+
+3. Implement dynamic imports for heavy components:
+   ```tsx
+   const Chatbot = dynamic(() => import('@/components/chat/Chatbot'), {
+     loading: () => <ChatbotSkeleton />,
+     ssr: false,
+   });
+   ```
+
+---
+
+### 4.3 Edge Caching Strategy
+
+**Current State:** Static assets cached for 1 year (good)
+
+**Additional Recommendations:**
+1. Configure Vercel Edge Config for dynamic content:
+   ```typescript
+   // Cache API responses at edge
+   export const runtime = 'edge';
+   export const revalidate = 60; // 1 minute
+   ```
+
+2. Implement stale-while-revalidate for blog posts:
+   ```typescript
+   export async function generateStaticParams() {
+     return blogPosts.map((post) => ({ slug: post.slug }));
+   }
+
+   export const dynamicParams = true;
+   export const revalidate = 3600; // 1 hour
+   ```
+
+3. Use ISR (Incremental Static Regeneration) for portfolio projects
+
+---
+
+### 4.4 Content Delivery Optimization
+
+**Recommendations:**
+1. Enable Brotli compression (Vercel default)
+2. Use HTTP/2 Push for critical resources
+3. Implement preload hints:
+   ```html
+   <link rel="preload" href="/fonts/inter.woff2" as="font" crossorigin />
+   <link rel="preload" href="/hero-portrait.avif" as="image" />
+   <link rel="preconnect" href="https://api.deepseek.com" />
+   ```
+
+---
