Shopify Developer | Theme Development, UI/UX, Speed Optimization

**Shopify Developer specializing in Shopify theme development, Liquid customization, custom sections, store improvements, speed optimization, bug fixing, and third-party integrations.** I help Shopify store owners build, customize, optimize, and maintain reliable e-commerce stores. Whether you need a small Shopify theme modification, custom functionality, performance improvements, or ongoing technical support, I can help. ### Shopify Development My Shopify services include: • Shopify development and customization • Shopify theme development • Shopify theme customization • Shopify 2.0 / Online Store 2.0 • Shopify Liquid / Custom Liquid development • Custom Shopify sections and blocks • Custom product and collection templates • Shopify product page customization • Shopify collection page customization • Cart and checkout-related customization • Shopify app installation and integration • Third-party API integrations • Metafields and Metaobjects • HTML, CSS and JavaScript development • Responsive and mobile optimization • Shopify speed optimization • PageSpeed and Core Web Vitals optimization • Bug fixing and troubleshooting • Theme updates and migration • Store migration • SEO-related technical improvements • Ongoing Shopify maintenance and support I am particularly comfortable working with existing Shopify stores where something needs to be fixed, improved, redesigned, optimized, or extended with custom functionality. I can investigate issues in an existing theme, modify Liquid templates, create reusable sections, customize product or collection pages, integrate third-party services, improve mobile layouts, fix JavaScript and CSS problems, and optimize store performance. ### E-commerce Development Experience I have been working in web development since 2009 and have extensive experience with e-commerce platforms. In addition to Shopify, I have many years of professional experience with PrestaShop. I started working with PrestaShop around version 1.2 and have worked with stores ranging from older PrestaShop versions to modern PrestaShop 8 and 9. This background gives me strong experience not only with frontend development but also with: • PHP and MySQL • JavaScript • HTML and CSS • APIs and third-party integrations • Payment and shipping integrations • E-commerce databases • Product and catalog architecture • Performance optimization • Server and PHP issues • Debugging complex e-commerce problems ### PrestaShop Development Although my current focus is Shopify, I also provide professional PrestaShop development, including: • PrestaShop module development • PrestaShop theme customization • PrestaShop upgrades and migrations • Bug fixing • Payment and shipping modules • API and ERP integrations • Performance optimization • PrestaShop 1.6 / 1.7 / 8 / 9 support ### Long-Term Shopify Support Many e-commerce stores do not need a full redesign — they need a reliable developer who can quickly understand an existing store and make changes without breaking what already works. I am available for both one-time Shopify tasks and ongoing development. Typical tasks include: • Fixing Shopify theme bugs • Adding or modifying theme sections • Liquid customization • Product page improvements • Collection page improvements • Mobile layout fixes • App-related modifications • Custom JavaScript functionality • Shopify performance optimization • Store maintenance • Technical troubleshooting If I apply for or accept a project, it means I am confident that I can complete it properly. My goal is not only to finish the current task but to become the developer you can contact again whenever your Shopify store needs another improvement.
