Slow loading speeds on websites is a very common problem that can really hurt your SEO. While different graphical libraries can create a visually stunning website they are usually very slow compared to pure HTML/CSS sites.
I can rewrite you site without any libraries and help you achieve 95+ rating in PageSpeed Insights even on mobiles! You page will remain the same visually, but it's speed and size will be a whole lot better!
Rewriting your landing page is usually enough to get all the SEO benefits!
