Hey, first time discovering this 'roast my website' site/forum.
I have taken a quick scan though your site and can see alot of the elements are either misplaced or too big for the allocated containers.
Your as featured on - is very prominent, both desktop and mobile, I would suggest placing that below your top of the fold 'hero' section. Especially on mobile...
You have a lot of text that needs addressing, as it looks too much and squished together in certain areas. To some degree unreadable and unrelating to what I'm viewing - ref shopify services etc etc
Menu tab - mobile is too far down and in a weird place, 'central below the top of fold'
Testimonials section - the blocks are very large and take over the entire screen and looks cluttered - so maybe try and simplify them a little so they're easier to read 'Inline'
You have three footer menus on the home page which is very confusing
Hope that's a little snippet of guidance :)
