Optimize (loading speed/CWV) Shopify website, it is a clothing e-commerce website

I am looking for a Freelancer to help me optimize a Shopify clothing ecommerce website. My main goal is to improve both the loading speed and Core Web Vitals of the website. I have been experiencing poor server response, page elements not loading quickly, and slowness navigating the page, resulting in a poor performance score in loading speed tests. It is urgent that I receive help as soon as possible to resolve this issue.
