Senior Shopify developer with 11+ years of full-stack experience and 7+ years building and optimizing Shopify storefronts. I custom-code high-converting landing pages, product pages, and reusable Online Store 2.0 sections using Liquid, JavaScript, HTML, and CSS. My work combines CRO, Core Web Vitals, GA4/GTM, A/B testing, and conversion-focused copywriting to improve page speed, engagement, add-to-cart rate, average order value, and revenue. Previous work includes Shopify platforms supporting 4.2M monthly sessions and $85M in annual GMV, with conversion improvements of up to 18%. I collaborate closely with designers, creative strategists, and copywriters, using Claude to accelerate page development and Higgsfield.ai to support creative iteration. I can take a landing page from concept and wireframe through native Shopify implementation, QA, launch, and ongoing optimization.
