What I'm looking for

I’m looking for a role where I can build and optimize Shopify-focused e-commerce experiences, integrate APIs and payments, and apply AI for personalization, automation, and data-driven conversion improvements—while owning performance, UX, and measurable outcomes.

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.
