I assume you already have read what I do from my profile. So here's in this Gig I'll will check your website for design errors.
There are many websites running those have Consistency, alignment, repetition and proximity issues or might be there's a little or big problem with the design.
I'll also check if your website or landing page have any usability problem like regarding CTA or any other flow that might create a problem to the user.
Thank you :)
