What I'm looking for

I seek remote, collaborative roles building Shopify/Shopify Plus storefronts and custom apps, focusing on performance, conversion optimization, and scalable integrations.

I am a Shopify Fullstack Developer with over nine years building and optimizing Shopify themes, custom apps, and storefront integrations. I specialize in Liquid, React.js, Node.js, GraphQL, and modern web technologies, and I deliver scalable e-commerce solutions that improve conversion and performance.

I have a proven record of implementing analytics, A/B testing, and integrations across Shopify Plus and standard Shopify stores, contributing measurable lifts in conversion rates and user engagement. I thrive working remotely and collaborating with distributed teams to turn design assets into production-ready, high-performing storefronts.
