I've been building on Shopify since 2014 - custom themes, embedded apps, Shopify Plus stores, and everything in between. With 10+ years of hands-on experience and a track record of leading long-term, high-value projects, I bring both deep technical expertise and the reliability that comes with senior-level ownership. My core focus is Shopify in its full depth. Shopify Development: Liquid · Storefront & Admin API (REST + GraphQL) · App Bridge · Polaris · Theme Extensions · Checkout Extensibility · Metafields & Metaobjects · Section Rendering API · Markets & Geo-IP · Shopify CLI / GitHub workflow · OS 2.0 · Dawn · Hydrogen (Headless) App & Backend Development: Embedded Shopify apps · Node.js / Fastify · PHP / Symfony · Python / Flask · REST APIs · Webhooks · MySQL · PostgreSQL Frontend & Performance: JavaScript (ES6+) · React · HTML5/CSS3 · Figma-to-Liquid · Core Web Vitals · LCP/CLS optimization · Three.js · Canvas API · Swiper.js · etc Beyond code, I understand what merchants actually need — fast load times, clean architecture, maintainable codebases, and solutions that scale. I've worked across DTC and B2B stores, handling everything from greenfield theme builds to complex app integrations, performance overhauls, and long-term maintenance. I'm available for full-time or part-time remote engagements. If you're looking for a senior developer who can own the technical side of your Shopify store or product - let's talk.

I build fast, accessible, conversion-optimized Shopify themes — clean Liquid architecture, native API integrations, zero unnecessary app dependencies. ──────────────── WHAT I COVER ──────────────── ⚡ Liquid, JavaScript & Shopify APIs 🚀 Performance, SEO & Accessibility 🧩 App Extensions & Shopify Functions 🔌 App Integration & Store Health 📈 CRO Implementation ──────────────── ⚡ Liquid, JavaScript & Shopify APIs Custom theme code built on Shopify's native APIs — no bloat, no unnecessary apps. Custom Liquid · Metafields & metaobjects · AJAX API · Section Rendering API · Recommendations API · Storefront API · Vanilla JS · Modern CSS I write semantic, maintainable Liquid that integrates directly with Shopify's native APIs. Metafields and metaobjects replace app-dependent data layers. The AJAX and Section Rendering APIs power dynamic UX without full-page reloads. The Storefront API enables headless and hybrid builds. All JavaScript is vanilla — no jQuery, no framework overhead. OS 2.0 architecture · JSON templates · Dynamic sections · Theme blocks · Headless Shopify · Hybrid storefront · Liquid filters · Global sections ──────────────── 🚀 Performance, SEO & Accessibility Speed, structure, and inclusivity built into the theme — each one reinforcing the others. Core Web Vitals · LCP / INP / CLS · Lazy loading · Render-blocking audit · Structured data · Canonical tags · WCAG accessibility · ARIA markup Core Web Vitals directly affect search ranking and conversion. I audit and resolve LCP bottlenecks (image sizing, preloading, critical CSS), INP issues (event handler debouncing, task splitting), and CLS problems (reserved space, font swap). Structured data (JSON-LD) for products, breadcrumbs, and FAQs improves rich snippet eligibility. WCAG 2.1 AA compliance and ARIA markup ensure the store works for every customer and passes automated accessibility audits. JSON-LD schema · Open Graph · Rich snippets · Font optimization · Critical CSS · Image compression · Semantic HTML · PageSpeed 90+ ────────────────── 🧩 App Extensions & Shopify Functions Extending checkout and post-purchase surfaces without touching core platform code. Checkout UI extensions · Shopify Functions · Post-purchase extensions · WebAssembly · PCI-compliant sandbox · Custom discount logic · One-click upsell Checkout UI extensions replace legacy checkout.liquid for Shopify Plus stores — adding upsells, custom fields, and trust badges inside a PCI-compliant sandbox. Shopify Functions allow custom discount logic, shipping rules, and payment filtering at the platform level. Post-purchase extensions capture upsell revenue after payment without re-entering checkout flow. Checkout branding API · Delivery customization · Payment customization · Order routing logic · Discount stacking · Bundle discounts ───────────────── 🔌 App Integration & Store Health Evaluating, installing, and managing App Store apps cleanly inside a live store. App evaluation · Permission scope review · Theme blocks & app embeds · Script tag audit · Conflict resolution · Clean uninstall Not every problem needs a custom build — but every app needs proper evaluation. I review permission scopes, script tag injection, and theme block conflicts before installation. When apps are removed, I audit and clean residual code, Liquid snippets, and asset files to prevent performance degradation. I resolve conflicts between competing apps and establish clean embed patterns that keep the theme editor predictable. Residual code cleanup · App vs custom build analysis · Third-party script management · Tag manager integration · App performance impact audit ───────────────── 📈 CRO Implementation Converting briefs into theme code across product, cart, and checkout — built to test and measure. Sticky ATC · Quick-view drawers · Cart drawer · Free shipping bar · In-cart upsell · Figma-to-Liquid · Feature flags · A/B test structure CRO work lives or dies by implementation quality. Sticky ATCs, quick-view drawers, and cart drawers are built with Section Rendering API and AJAX — no page reloads, no layout shift. Free shipping bars and in-cart upsells pull live cart data. Figma-to-Liquid translation preserves pixel-accurate design intent while maintaining theme editor flexibility. Feature flags allow new components to ship to a percentage of traffic for A/B testing before full rollout. Split testing · Conversion tracking · GTM integration · Heatmap-ready markup · Bundle builder UI · Exit intent · Product recommendations · Upsell flows ───────────────── Shopify Development | Liquid (Programming Language) | Shopify Theme Development | Shopify Plus | Conversion Rate Optimization (CRO) | Web Performance | Shopify App Integration | JavaScript | API Integration | Web Accessibility (WCAG) | Front-End Development | Technical SEO | E-commerce Development | UI/UX Implementation | Core Web Vitals
