Senior Shopify & Full Stack Engineer transforming visions into high-converting, conversion-optimized stores.
What I'm looking for
I’m a Senior Shopify & Full Stack Engineer with over 6 years of experience building stunning, user-friendly e-commerce websites that are optimized for conversions. I tailor Shopify themes and functionality to meet unique business needs, developing custom storefront experiences and Shopify apps, then integrating third-party APIs to expand real functionality.
My focus is measurable growth: I improve conversion rate through A/B testing and GT4 events, while strengthening visibility with search engine optimization and performance work for faster UX and checkout flows. I also bring full-stack execution using Liquid, JavaScript, HTML/CSS, React, Node.js, and REST APIs, and I collaborate closely to plan, deploy, troubleshoot, and maintain scalable Shopify architecture.
