Hi,
If I get the opportunity. I'll try to fix all your page speed problems such as overall page load speed, FCP, LCP, SEO, performance, page weight (size), Image compression etc.
I will also fix the responsiveness of the pages and will try to make them look professional.
I already have done these kinds of optimations in my organization. I am aware of the web-vitals thing to make an app as light and accessible as possible.
Nevertheless, only the outcome will tell all.
