Senior Shopify Developer | Shopify Plus, Custom Themes & CRO

I develop Shopify stores for established brands - My recent Shopify projects include CRO-focused product and landing page redesigns, A/B test implementation, and full-store redesigns. I help ecommerce brands turn designs and growth ideas into custom Shopify storefronts that are built to perform and easy to manage 🏆 Top Rated | 100% Job Success | 5 years of Shopify experience I work with brands that need more than a standard theme setup: a storefront redesign, custom product functionality, a subscription experience, or a developer who can support ongoing improvements. I collaborate with founders, designers, and growth teams to turn requirements into tested, working Shopify experiences 🛠️ SHOPIFY DEVELOPMENT & CUSTOM THEMES Custom Shopify theme development and Online Store 2.0 customization using Liquid, JavaScript, HTML, and CSS. I build reusable sections, product and collection templates, navigation, custom cart drawers, and flexible content structures using metafields and metaobjects. Your team can manage content through the Shopify theme editor without needing a developer for every change 🎨 FIGMA TO SHOPIFY & WEBSITE REDESIGNS Accurate implementation of Figma designs across desktop, tablet, and mobile. From full Shopify website redesigns to individual templates, I translate your brand’s typography, layouts, and interactions into responsive storefronts. I work with both existing themes and custom codebases, reviewing dependencies before making changes. 🛒 PRODUCT PAGES, LANDING PAGES & CRO Shopify product-page and landing-page development in custom Liquid or Replo for product launches, campaigns, and conversion rate optimization (CRO). This includes purchase selectors, bundles, sticky add-to-cart, cart upsells, free-gift logic, and product recommendations. I also implement A/B test variations with Intelligems and Elevate, working with your growth team to build and test changes across the shopping journey 🔁 SUBSCRIPTIONS & SHOPIFY PLUS Recharge, Skio, and Loop subscription integrations, including custom selling-plan selectors, delivery frequencies, subscription-only offers, and post-purchase upgrade flows. For Shopify Plus stores, I implement supported checkout customizations through Checkout Extensibility. Subscription pricing, product options, and cart behavior are tested together as part of the customer experience. ⚙️ CUSTOM FEATURES, INTEGRATIONS & APP MINIMIZATION Custom product builders, interactive storefront features, product-option logic, and third-party integrations. I connect the storefront with tools such as Klaviyo and review platforms, and work on inventory-related integrations and custom workflows. When an app adds unnecessary complexity, I assess whether a lightweight custom solution is more practical. The priority is maintainable functionality, not removing apps at the expense of reliability ⚡ SHOPIFY SPEED OPTIMIZATION & TECHNICAL SEO Theme performance improvements, JavaScript and CSS cleanup, image-loading optimization, and mobile usability fixes. I identify unnecessary scripts and app dependencies and address theme-level issues affecting page speed and Core Web Vitals. I also implement technical SEO foundations, including heading structure, metadata, and redirect checks during redesigns, with attention to preserving existing URLs and search visibility. 🤝 ONGOING DEVELOPMENT & TECHNICAL SUPPORT Long-term Shopify support, theme updates, bug fixes, code refactoring, and new feature development. I help teams maintain their existing store while implementing the next round of improvements. You work directly with me on technical decisions, progress updates, and delivery. ✅ HOW I APPROACH YOUR PROJECT I start by reviewing your store, designs, requirements, and existing setup. You receive a defined scope, realistic estimates, and clear explanations of the technical trade-offs. Theme development takes place in an unpublished theme, with mobile and cross-browser testing before launch. I build editable components, explain how custom features work, and coordinate the release with your team. The goal is a storefront that represents your brand, supports your commercial priorities, and remains practical to manage after delivery 📩 Send me an invitation or message with your store URL, design files, or the functionality you need. I’ll review the requirements and help define the right development approach
