I’m a Senior Shopify Developer with 10+ years of experience building and optimizing high-performance eCommerce storefronts using Shopify Liquid, HTML5, CSS3/SCSS, and JavaScript. I specialize in Shopify theme development, API integrations, performance optimization, and scalable frontend architecture.

In my recent work as a Senior Shopify Developer (07/2023–04/2026), I developed and customized advanced Shopify themes using Liquid, HTML5, SCSS, and JavaScript. I implemented and maintained third-party Shopify app integrations and custom API connections, then optimized storefront speed, Core Web Vitals, and mobile responsiveness to improve conversion rates and customer engagement. I also collaborate closely with UX/UI designers and marketing teams to deliver responsive, user-focused storefront experiences.

Before that, I built responsive, conversion-focused Shopify storefronts with strong cross-browser compatibility and accessibility (including WCAG), and I used performance optimization and A/B testing to improve engagement and checkout completion. I’ve also worked across ShopifyPlus projects, strengthened technical SEO structure, and maintained clean, maintainable codebases while contributing to code reviews, deployment processes, and Agile/Scrum delivery.
