Optimize Technology Icon Images
High Impact+25 points estimated
Why It Matters
Images are massively oversized, with the React icon alone wasting 349KB being displayed at 96x85 from a 3840x3417 source.
How to Fix
Resize technology icons to their actual display dimensions (96x96px) before uploading. Convert PNG files to WebP format for better compression. Create responsive image variants using Astro's built-in image optimization with the Image component.
0Poor
What This Score Means
A score of 0 falls in the "Poor" range (50-89). While it is better than poor (0-49), you should aim for 90+ to provide an optimal user experience and maximize SEO benefits.
This site is slower than approximately 35% of similar sites. The main issues affecting performance are image optimization, JavaScript execution time, and layout stability.
Addressing these issues could improve your conversion rate by 15-20% and boost your search engine rankings.

AI Performance Analysis
This website has severe performance issues with a failing score of 0/100. The biggest problem is oversized images that are wasting 789 KB of bandwidth - for example, a React logo image is 3840x3417 pixels but only displayed at 96x85 pixels, which is massively inefficient. The page takes 4.6 seconds to visually load content and 2.6 seconds for the first paint, both unacceptably slow for modern web standards. Additionally, render-blocking CSS and font files are delaying initial page display, and JavaScript code is causing forced reflows that hurt performance further.
Other Optimization Recommendations
Eliminate Render Blocking Resources
High Impact+20 points estimatedWhy It Matters:
CSS and font files are blocking initial page render, delaying First Contentful Paint to 2.6 seconds.
How to Fix:
Inline critical CSS directly in the HTML head for above-the-fold content. Use font-display: swap in your Google Fonts CSS to prevent render blocking. Defer non-critical CSS using media='print' onload technique or Astro's client:load directive.
Fix Forced Reflow Issues
Medium Impact+10 points estimatedWhy It Matters:
JavaScript is causing 112ms of forced reflows by reading layout properties after DOM changes, blocking the main thread.
How to Fix:
Batch DOM reads before DOM writes to avoid layout thrashing. Cache geometric properties like offsetWidth instead of repeatedly querying them. Move layout-triggering JavaScript to requestAnimationFrame callbacks for smoother performance.
