Shopify developer with strong WordPress and WooCommerce expertise - I build, rebuild, and optimize ecommerce stores on both platforms: custom Liquid themes, migrations, integrations, speed, and CRO. 20,000+ hours across 126 Upwork contracts. My agency, Yelk, has billed another 30,300. In the age of AI-generated code, anyone can ship a store that looks right. Security, technical SEO, and page speed are what get skipped - and they surface later, expensively. Preventing and fixing that is a large part of what I get hired for. SHOPIFY & SHOPIFY PLUS - Shopify and Shopify Plus store development - Custom Liquid theme development and customization - Store redesigns and Figma-to-Shopify implementation - App and API integrations - Speed and Core Web Vitals optimization - Conversion rate optimization - WooCommerce-to-Shopify migrations - Complex product, checkout, and storefront functionality - Ongoing development and support WORDPRESS & WOOCOMMERCE This is where most of my 20,000 hours come from, and I still take this work on: - Custom WordPress and WooCommerce development - Custom themes and plugin development - Enterprise migrations and store redesigns - Speed, Core Web Vitals, and technical SEO - API and third-party integrations - Ongoing development and support WHY WORKING ACROSS BOTH MATTERS TO YOU Because I know both ecosystems from the inside, I can tell you honestly whether to fix your current store, rebuild it, or migrate to Shopify. Most Shopify developers can only recommend Shopify. It also means migrations don't worry me. I know what breaks on the way out, not just what to set up on the way in. HOW I WORK I've been both a senior developer and a manager of dev teams, so I think about what actually decides whether a project succeeds: realistic scope, code quality, QA, deadlines, maintainability. You won't chase me for updates, and I'll tell you when something isn't worth building before you pay for it. That's why clients stay: 100% of my client relationships on Upwork run longer than 90 days. I don't launch a store and disappear. RECENT WORK Shopify builds for health, wellness, retail, clothing, and luxury brands. A 2,700-hour ecommerce platform rebuild for a manufacturing company. An enterprise WordPress migration. A custom WooCommerce plugin built on Node.js. Beyond ecommerce, I also build Laravel and PHP platforms - scalable SaaS products, B2B and B2C web applications, and REST/GraphQL API design and integration. For larger builds, I also work with Node.js, React, Vue, Next.js, MySQL, PostgreSQL, and Docker. HOW WE START If you're not sure yet, we don't start with the full project. I run a paid store audit or a small first milestone, so you can see the code, the communication, and the pace before committing the budget. Tell me what you're building.
