I needed a small tweak to my Shopify Online Store that had to do with metafields. Shopify has limitations to customizations for individual products, but they can be solved with metafields. I tried to create and implement, myself, but just couldn't get it right. I reached out to Serge, and he resolved the issue, quickly.

I would like to continue working with you, maybe even off the platform. Maybe agreeing on what needs to be fixed and a few hours and paying by the hour. I'm not an expert but I know how to do something. I would like the sites to work well and make something.
