Jatin M.

Shopify developer behind stores and custom apps that process 19,000+ orders a month across the US, UK and GCC. I build what off-the-shelf apps can't: custom checkout and cart apps, subscription logic, payment and marketplace integrations, and fast premium storefronts. Brands usually come to me when an app stops being enough. RECENT WORK - Custom checkout & add-to-cart app for a US supplement brand on Shopify Plus (8,000+ orders/month) - Custom Recharge gift subscriptions for a US kids' supplement brand (4,700+ orders/month) - HyperPay & Tap Payments customization plus a custom app for a GCC food brand (6,000+ orders/month) - Shopify Markets: US duties at checkout with DDP shipping - Lulu Direct print-on-demand integration and a Shopify-DSCO integration for a Nordstrom Rack vendor - XEO: a multi-tenant platform that syncs brand catalogs to retailer Shopify stores with field-level ownership rules - Native back-in-stock system with zero third-party apps, and an embedded NFC verification & returns app Invite me to your job and I'll reply with a short Loom showing how I'd build your solution, before any contract starts.
