CRO | Shopify Plus / Wordpress / WebFlow Dev | Headless | Integrations
I’m Muhammad Aziz, a Senior Shopify Plus & Commerce Engineer with 8+ years of experience building, scaling, integrating and optimizing high-performing eCommerce stores. Shopify Plus is my core specialization, with broader hands-on experience across BigCommerce, WooCommerce, Webflow, WordPress, Squarespace and other eCommerce platforms. This gives me a wider perspective on commerce architecture, platform migrations, integrations and the technical challenges involved in building scalable eCommerce solutions. I work beyond traditional Shopify theme development, helping growing brands solve complex commerce challenges across: • Shopify Plus & custom storefront development • Headless commerce with Hydrogen, React & TypeScript • Custom Shopify apps & functionality • Admin API, Storefront API, GraphQL & webhooks • ERP, WMS, CRM, fulfilment & third-party integrations • Checkout Extensibility & Shopify Functions • Shopify B2B & complex commerce workflows • Shopify Markets & international commerce • CRO, Core Web Vitals & performance optimization • Klaviyo & eCommerce platform integrations • High-traffic/BFCM readiness & ongoing technical support Whether you need to integrate Shopify with an ERP/WMS, build custom functionality, migrate between commerce platforms, improve storefront performance, optimize conversions or architect a more scalable commerce solution, I can help from technical planning through implementation and launch. My core stack includes Shopify Liquid, JavaScript, TypeScript, React, Node.js, Hydrogen, GraphQL, HTML/CSS, Shopify APIs, Git/GitHub and modern AI-assisted development workflows using tools such as Codex, Claude and Cursor. I also bring strong CRO experience, so my approach isn’t limited to making features technically work. I consider performance, customer experience, conversion, maintainability and long-term scalability throughout the build. Over the years, I’ve worked across complex Shopify and eCommerce builds, integrations, migrations, international commerce, performance optimization and ongoing development. If you need a senior commerce engineer with deep Shopify expertise and an understanding of the wider eCommerce ecosystem, I’d be happy to discuss your project.
