I'm Manish Kumar, an IIT Dhanbad grad and full-time Senior Software Developer, freelancing as a Shopify expert for 3+ years. I’ve worked with 10+ global D2C brands, fixing broken themes, building custom sections, integrating APIs, and optimizing stores for speed and conversions — all without relying on bloated apps. From custom modals, wishlist logic, Klaviyo flows to GA4 event tracking — if it’s technical and on Shopify, I’ve probably done it.
