Hello! I saw your job posting and understood that I would be able to help you with it. I used to work with HTML, Css, Javascript and JQuery. Also, I have a good experience working with Shopify and your work is easy for me. If you decide to work with me, I can guarantee that at the end you'll get the work with a high quality and in good terms. If you contact with me, I show you my previous work in shopify.
Thanks for attention.
Arthur
