Dear client,
I understood what needs to be built. I am quite experienced in building the pages in Bootstrap 4, HTML, CSS, JavaScript, jQuery. I also have good knowledge of SHOPIFY platform and I can do this work quite well.
I can build your product pages well, and make them responsive so that they work well on desktop, mobile, and tablet devices. Also I can achieve this even without Bootstrap if you do not Bootstrap to be applied.
Can you please share the images/designs?
