Website speed for SEO purposes

we are looking for a developer with the ability to help us improve the overall performance of our website (https://espiritorebelde.pt/store/pt/)

we want help with the fowlling metrics
LCP (Largest Contenfull paint) refers to a page loading performance. It covers
the perceived loading speed. Or in other words how long does it take for the website
to start displaying elements that are most important to the user, like the product
images, videos, order customization tools, etc.

FID (First Imput Delay) Measures the responsiveness of a webpage. In other
words this metric measures the time between a user’s interaction with a page
element and when the browser can respond to that interaction. Ex: when the user
clicks the purchase button how long does the website take to process that
information.

CLS (Cumulative Layout Shift) refers to the frequency of unexpected layout
changes and a web page’s overall visual stability. Ex: When you’re reading a
paragraph on a blog, and buttons, ads, and videos keep loading as you’re reading,
which keeps bumping the paragraph down the page, so you have to keep scrolling to
read it.
