Rajat was great! It was my first time using him and I have now found my new go to Shopify developer. He was quick to respond. Great English fluency, knowledgeable and responsive. He also understood immediately what I was trying to accomplish. I would definitely encourage anyone looking for a Shopify developer or Flow developer to look here.
