Shopify Expert | Full-Stack Developer | AI & Custom Apps

Top Rated Plus Shopify Expert & Full-Stack Developer. I build and optimize Shopify stores, custom apps, integrations, and e-commerce solutions—and use AI-assisted development workflows to solve complex problems faster and more efficiently. I help e-commerce businesses with: • Custom Shopify & Shopify Plus development • Custom Shopify apps, APIs, and backend integrations • B2B, dealer, quotation, approval, and custom order workflows • Shopify migrations, product/variant migration, redirects, and SEO • Shopify performance optimization & Core Web Vitals • Subscription, bundle, upsell, and cross-sell experiences • Custom product options, personalization, pricing, and configurators • ERP, CRM, inventory, analytics, and third-party integrations • Liquid theme development and Figma-to-Shopify implementation • AI-assisted Shopify development and AI integrations I work across the full stack with Shopify/Liquid, JavaScript, React, Next.js, Node.js, MySQL, APIs, and modern AI development tools. This allows me to take ownership of a project beyond the theme layer—from architecture and custom development to integrations, optimization, testing, and launch. I've worked on complex Shopify projects involving B2B commerce, 80,000+ product variants, custom configurators, subscriptions, ERP/CRM integrations, and significant storefront performance improvements. My goal isn't just to make your Shopify store work. I focus on solving the underlying business or technical problem and delivering a solution that is reliable, maintainable, scalable, and valuable to your business. If your Shopify store has outgrown standard theme customization, or you have a complex integration, migration, performance issue, or custom e-commerce requirement, send me the details. I'll help you find the right solution and turn it into a working Shopify implementation.
