What I'm looking for

I seek a remote or hybrid role focusing on Shopify/commerce development where I can lead theme and app projects, optimize performance, and drive measurable growth while collaborating with product and marketing teams.

I am a Senior Shopify Developer with over 8 years of experience delivering high-performance, scalable Shopify stores, custom themes, apps, and integrations for client needs. I specialize in Liquid, JavaScript, HTML, CSS, Shopify Plus features, and performance optimization to boost conversions and user experience.

I've led end-to-end development of high-traffic Shopify stores and implemented features such as custom checkout processes, dynamic pricing, product bundling, subscription services, and advanced inventory management, contributing to measurable increases in sales, retention, and organic traffic.

I collaborate closely with marketing and product teams to run A/B tests, improve SEO, and deliver client training and documentation, ensuring smooth post-launch management and continuous improvement of e-commerce platforms.
