About Me
Crafting High-Performance Shopify Stores & React.js Applications
Hi, I'm Muhammad Ehtesham — a Shopify Developer and Front-End Engineer with 2+ years of hands-on experience building custom Shopify 2.0 storefronts and dynamic React.js single-page applications. I specialize in Liquid templating, Checkout Extensibility, Metaobjects, and headless commerce via the Shopify Storefront API (GraphQL).
I obsess over the details that drive real business results — Core Web Vitals scores, Largest Contentful Paint, conversion rate optimization, and pixel-perfect mobile-first UIs. Whether you need a blazing-fast Shopify store, a custom React.js SPA, or a Stripe & PayPal payment integration — I deliver clean, scalable code with zero shortcuts.
