Convert Images to Modern Formats
Medium Impact+1 point estimated
Why It Matters
Your profile image wastes 85KB which could be reduced by 30-50% with modern formats.
How to Fix
Install WebP Express or ShortPixel plugin to automatically convert PNG/JPEG to WebP. Replace your profile image at /resume/Atg-clean.png with WebP version. Add fallback support for older browsers using <picture> element in your theme template.

AI Performance Analysis
This WordPress site has excellent performance with an outstanding score of 99/100, indicating very fast loading times for users. The biggest remaining issue is render-blocking CSS that's delaying page rendering by about 130ms, specifically the main stylesheet that prevents content from appearing until it's fully downloaded. Additionally, the site could benefit from extending cache lifetimes for Cloudflare scripts (saving about 5KB) and converting the profile image to a modern format like WebP to reduce its size by 83KB. These are relatively minor optimizations that would polish an already well-performing website.
Other Optimization Recommendations
Eliminate Render Blocking CSS
High Impact+3 points estimatedWhy It Matters:
Your main stylesheet blocks initial page render, delaying both FCP and LCP by 150ms.
How to Fix:
Inline critical CSS directly in your WordPress theme's header.php for above-the-fold content. Use loadCSS or a plugin like Autoptimize to defer non-critical CSS. Consider splitting your style-new.css into critical and non-critical portions.
Extend Cache Lifetimes for Assets
Medium Impact+1 point estimatedWhy It Matters:
Short cache durations force unnecessary re-downloads on repeat visits, slowing LCP by 150ms.
How to Fix:
Configure Cloudflare to cache static assets for at least 1 year (31536000 seconds). Add cache-control headers via WordPress .htaccess or use W3 Total Cache plugin. Set longer cache times for your theme CSS and Cloudflare's beacon.min.js.
