What I'm looking for

I’m looking for a role building high-performance ecommerce storefronts, ideally with Shopify/Shopify Plus. I want to work in a remote international team, own storefront development end-to-end, and collaborate closely with design and product to drive SEO and conversions.

I’m a Full Stack Developer with 5+ years building ecommerce platforms and modern web applications. I specialize in Shopify and Shopify Plus development, combining JavaScript, TypeScript, React, Next.js, Node.js, and Liquid to create scalable storefront experiences.

I lead Shopify and Shopify Plus projects end to end—customizing themes with reusable sections/blocks, building advanced product and collection templates, and integrating REST APIs for marketing, subscriptions, analytics, and inventory. I’m focused on performance and outcomes too: Core Web Vitals, SEO, mobile UX, and conversion-oriented frontend improvements—while collaborating across design, product, and engineering in remote international teams.
