🔧 Immediate Fixes

Step 1: Image Optimization

A. Optimize Profile Image

# Convert dp.png to WebP and optimize
# Target: 50KB max, 200x200px for mobile

Manual Steps:

  1. Open dp.png in any image editor
  2. Resize to 200x200px (or 400x400px for retina)
  3. Save as WebP format
  4. Compress to <50KB

B. Optimize Large Images

# Convert website.jpg to WebP
# Target: 200KB max

Step 2: CSS Optimization

A. Remove Unused CSS

/* Remove unused font imports */
/* Keep only essential fonts */

B. Minify CSS

# Minify style.css
# Remove comments and whitespace

Step 3: Font Optimization

A. Reduce Google Fonts

<!-- Current: Loading 15+ fonts -->
<!-- Optimized: Load only 3-4 essential fonts -->
<link href="https://fonts.googleapis.com/css2?family=Inter:wght@400;600;700&family=Playfair+Display:wght@400;600&display=swap" rel="stylesheet">

B. Font Display Optimization

/* Add to CSS */
@font-face {
  font-family: 'Inter';
  font-display: swap; /* Critical for performance */
}

📱 Mobile-Specific Optimizations

1. Responsive Images

<!-- Add responsive image sizes -->
<img src="dp.webp" 
     srcset="dp-200.webp 200w, dp-400.webp 400w"
     sizes="(max-width: 768px) 200px, 400px"
     alt="Ambreen Hanif"
     loading="lazy">

2. Critical CSS Inline

<!-- Inline critical CSS for above-the-fold content -->
<style>
  /* Critical styles only */
  .hero-section { /* ... */ }
  .site-header { /* ... */ }
</style>

3. Defer Non-Critical CSS

<link rel="preload" href="/assets/css/style.css" as="style" onload="this.onload=null;this.rel='stylesheet'">
<noscript><link rel="stylesheet" href="/assets/css/style.css"></noscript>
