Hey, i had a quick look at your site and first two things that i would improve is optimisation and design.
When it comes to optimisation i use this websites:
GTmetrix is a free tool to test and monitor your page's performance. Using Lighthouse, GTmetrix generates scores for your pages and offers actionable recommendations on how to optimize them.

Score of your site for mobile devices:
This plugin is great for disabling js on pages where they are not needed:
Make your website load FASTER by stopping specific styles (.CSS) & scripts (.JS) from loading. It works best with a page caching plugin / service.

Small but very useful tip for images - u can expand Optimize images tab in gtmetrix and download optimised verion of images. I know their size is veeery small in most cases but it will improve your score.
By design i mean this:
-search bar doesnt have good visibility, especially on one or two of the images in slider, change images, add overlay to them, change font, add border to search bar, there are many things you can do. There has to be contrast between search bar and slider.
-text on a slider has the same problem.
-right border in menu looks weird
