Shopify store problems don't always stop at the theme. I help brands build custom functionality, fix checkout issues, connect third-party systems, and solve technical problems that standard apps can't handle. I'm a Top Rated Plus developer with 100% Job Success and $50K+ earned on Upwork. I have 12+ years of experience developing and maintaining production web applications, including Shopify Plus work for Sleefs and custom WordPress platforms for the Adoption platform. Some of the work I've done: Shopify custom development: Built product and variant management tools using the Shopify Admin GraphQL API, developed discount logic with Shopify Functions, and customized storefront functionality with Liquid and JavaScript. WooCommerce & WordPress: Developed custom PHP/Laravel functionality, payment workflows, CRM integrations, and solutions involving HubSpot, Gravity Forms, and third-party APIs. Performance & troubleshooting: Worked with Core Web Vitals, Cloudflare, caching, production debugging, and GA4/GTM and Meta conversion tracking. I enjoy working on the difficult parts of ecommerce: situations where a theme setting, another plugin, or a quick JavaScript fix isn't enough. My approach is straightforward: understand the issue, identify the root cause, implement the fix safely, and test the complete customer journey before releasing changes. Need help with a Shopify or WooCommerce issue? Send me a description of the problem or the project you want to build. I'll help you work out the best technical approach.
