Eliminate Render-Blocking CSS
Medium Impact+12 points estimated
Why It Matters
CSS files block initial page render for 620ms, delaying both FCP and LCP metrics.
How to Fix
Inline critical above-the-fold CSS directly in your Rails layout template. Move non-critical CSS like snowfall.css to load asynchronously using media='print' onload='this.media="all"' technique. Minify main.css to save 8 KiB and reduce unused CSS rules by 87%.

What This Score Means
A score of 39 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 critically low score of 39/100. The biggest problem is animated snowfall effects that are causing massive layout shifts (CLS score of 0.864), making the page visually unstable as content jumps around while loading. Additionally, the site is loading extremely slowly with an 8.9-second Largest Contentful Paint, primarily due to oversized images, unminified JavaScript/CSS files, and render-blocking resources. Removing or fixing the snowfall animation, optimizing images (which could save 842 KiB), and minifying code files could dramatically improve both stability and loading speed, potentially boosting the performance score by 40+ points.
Other Optimization Recommendations
Remove Snowfall Animation Effects
High Impact+25 points estimatedWhy It Matters:
Animated snowfall elements cause 0.864 CLS score with 15 layout shifts, severely impacting user experience.
How to Fix:
Disable the snowfall.css and related snowflake animations in your Rails application. Remove the snowfall script includes from your layout templates. If seasonal effects are needed, use CSS-only animations with fixed positioning that don't cause layout shifts.
Optimize and Compress Images
High Impact+18 points estimatedWhy It Matters:
Large images waste 842 KiB of bandwidth and delay LCP by 350ms, particularly the oversized project images.
How to Fix:
Resize project-6.webp from 3072x2008 to actual display size of 380x248 using ImageMagick in your Rails asset pipeline. Implement responsive images with srcset attributes. Add explicit width/height attributes to prevent layout shifts during image loading.
