Hey, I'm Zunnoon. I'm a Shopify developer specializing in Shopify theme development, Shopify store setup, and Shopify store optimization, and I also build full-stack web apps when a project goes beyond Shopify. Every completed project on this profile has been rated five stars.
𝗦𝗛𝗢𝗣𝗜𝗙𝗬 𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗠𝗘𝗡𝗧, 𝗧𝗛𝗘𝗠𝗘 𝗖𝗨𝗦𝗧𝗢𝗠𝗜𝗭𝗔𝗧𝗜𝗢𝗡 & 𝗦𝗧𝗢𝗥𝗘 𝗢𝗣𝗧𝗜𝗠𝗜𝗭𝗔𝗧𝗜𝗢𝗡
I handle Shopify theme development and rebrands, custom Shopify store setup, Liquid-based store customization, front-end UI fixes, custom product-page features (comparison tables, interactive selectors), multi-language and multi-currency configuration, and Shopify store speed and performance optimization.
Whether you need a Shopify store built, a theme customized, a specific feature developed, or an existing issue fixed, I focus on clean, reliable Shopify development that holds up under real-world use.
𝗙𝗨𝗟𝗟-𝗦𝗧𝗔𝗖𝗞 𝗗𝗘𝗩𝗘𝗟𝗢𝗣𝗠𝗘𝗡𝗧 (𝗥𝗘𝗔𝗖𝗧, 𝗡𝗘𝗫𝗧.𝗝𝗦, 𝗡𝗢𝗗𝗘.𝗝𝗦)
I build full-stack applications from the ground up and also diagnose and fix production issues on existing apps including API errors, CORS issues, unstable legacy code, broken functionality, and deployment problems. I work across JavaScript, React, Next.js, Node.js, MongoDB, and API integration, and I focus on finding the actual root cause rather than a patch that breaks again.

𝗛𝗢𝗪 𝗜 𝗪𝗢𝗥𝗞
Scope and pricing are agreed before work starts, with regular updates throughout the project so you always know what's being worked on and what's coming next.
My completed jobs range from same-day fixes to a four-month engagement, so I'm comfortable with both quick-turnaround Shopify tasks and longer-term Shopify or full-stack development projects.
I take the time to understand the actual problem before writing code, communicate clearly throughout, and focus on delivering a solution that's reliable, maintainable, and aligned with your goals.
Got a Shopify store that needs building, customizing, or optimizing? Or a full-stack application you need built from scratch, improved, or debugged?
