Squarespace to Shopify Migration
Chandan was really good to work with. He worked on a range of projects from my Shopify theme to helping me standup a bespoke application. As a small business I pushed him hard to move fast. I would have given 5 stars save for a slight reluctance to fully embrace AI tools to speed development. Overall though he was great to work with and I would call on him again.
