What I'm looking for

I seek roles focused on Shopify app/theme development where I can improve store performance, implement API integrations, and work collaboratively to deliver measurable merchant growth.

I am a Shopify App Specialist with over 6 years of experience building scalable, high-performance Shopify apps and custom themes. I focus on transforming complex e-commerce challenges into simple, effective, and maintainable solutions that deliver measurable business impact.

My work emphasizes performance, usability, and clean architecture; I have developed and released apps to the Shopify App Store, built Liquid-based themes with React and Node.js, and optimized stores for speed, SEO, and accessibility—improving performance up to 25% and achieving strong merchant satisfaction.

I collaborate cross-functionally to deliver projects on time and within budget, implemented Shopify Plus API integrations to streamline operations, and improved release workflows and CI/CD to shorten deployment cycles and increase merchant outcomes.
