What I'm looking for

I want to build and scale high-performing Shopify and WordPress e-commerce experiences—translating Figma into responsive UI—while owning Core Web Vitals, technical SEO, security, and automation to improve usability and site operations.

I’m a Senior Shopify and WordPress developer with 4+ years of experience building high-performing e-commerce websites, custom themes, plugins, and automation workflows. I bring strong engineering fundamentals with Liquid, PHP, JavaScript, and Git, and I’m comfortable turning Figma designs and wireframes into responsive, pixel-perfect, conversion-focused interfaces.

In my recent work, I’ve designed and developed performant Shopify themes using Liquid, metafields, and optimization scripts, while integrating secure APIs, payment gateways, and third-party tools to extend store functionality. I routinely audit frontend performance to reduce load times and improve user experience, and I’ve implemented automated inventory solutions to streamline store operations.

Across WordPress projects, I’ve handled everything from theme customization and core maintenance to structural issue resolution, plugin/database conflict fixes, and QA testing. I focus on security, scalability, and SEO outcomes—applying Core Web Vitals optimization, technical SEO, and deployment workflows—often supported by AI-assisted development, prompt engineering, and Gemini AI API integration configuration.
