Extend Static Asset Caching
Medium Impact+4 points estimated
Why It Matters
Short cache lifetimes force repeat downloads, wasting 83 KiB and slowing return visits.
How to Fix
Configure your hosting provider to set longer cache headers for static assets. Extend font files and images cache from 7 days to 1 year (31536000 seconds). Add cache-busting version parameters to filenames when content changes. This improves repeat visitor performance significantly.

What This Score Means
A score of 89 falls in the "Needs Improvement" 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
Your portfolio site has good performance with a score of 89/100, but there's significant room for improvement in loading speed. The biggest issue is oversized images that are much larger than needed - your images are 3840x1080 pixels but only displayed at 359x101, wasting 439 KB of data and causing your largest content to load in 3.5 seconds instead of the ideal 2.5 seconds or less. You can dramatically improve performance by resizing these images to match their display dimensions, implementing longer cache lifetimes for your fonts and images, and adding explicit width/height attributes to prevent layout shifts. These changes could easily push your score into the mid-90s and make your site feel much snappier for visitors.
Other Optimization Recommendations
Optimize Oversized Portfolio Images
High Impact+8 points estimatedWhy It Matters:
Images are 10x larger than needed, wasting 439 KiB and delaying LCP by 1.5 seconds.
How to Fix:
Resize portfolio images from 3840x1080 to actual display size of 359x101 pixels. Use responsive image tools or online compressors like TinyPNG. Convert to WebP format for additional 30% size reduction. Update img src attributes to point to optimized versions.
Add Image Dimensions Attributes
Medium Impact+3 points estimatedWhy It Matters:
Missing width/height attributes cause layout shifts as images load, hurting user experience.
How to Fix:
Add explicit width='359' height='101' attributes to all portfolio image elements. Update the three main gallery images first: formations list, employment section, and software skills. This prevents content jumping during load and improves CLS score.
