Shopify App Developer | Product Customization Shopify Plus Specialist

100% Job Success

4.8 (37 reviews)

Amalsad, India - 8:16 am local time

I build and scale Shopify stores, apps, and product customization experiences — with 43 completed Upwork projects, 3.5K+ hours delivered, and a 100% Job Success score.

With 10+ years in web and eCommerce development, I've delivered custom Shopify stores, Shopify Plus builds, and complex integrations for startups through established brands. I was part of the founding development team behind **Ultimate Product Options**, a Shopify app I helped build from the ground up — covering conditional logic, product options, image/color swatches, file uploads, add-on pricing, and product bundles — giving me hands-on experience with Shopify's Admin API, Storefront API, Functions, and Checkout/Theme App Extensions from the inside, not just the docs.

What sets me apart from most Shopify freelancers is that I've built the *app side*, not just themes — so I understand both the merchant-facing storefront and the backend app architecture that powers it.

If you need a new Shopify store, a custom app, Shopify Plus development, or performance/CRO work on an existing store, I can help you build something fast, maintainable, and designed to grow with your business.
