I build fast, custom-coded Shopify OS 2.0 themes and Liquid features that load in under 1.8 seconds on mobile and convert cold traffic without bloated page-builder apps. Over 40+ Shopify storefronts shipped (100% Job Success, Top Rated, $25k+ earned on Upwork), from regional enterprise builds for Abercrombie & Fitch and HollisterCo Indonesia to high-growth DTC brands across fashion, wellness, and CPG. Recent Client Outcomes: - Voli Wellness (DTC): Built custom tiered bundle selectors, slide-out AJAX cart drawer, and checkout upsells in native Liquid - lifted AOV by 18-24% with zero app subscription bloat. - Abercrombie & Fitch & HollisterCo ID (with MAP Group): Engineered modular Shopify OS 2.0 theme architecture with strict design-system fidelity and sub-2s load performance. - Wearsun Miami & Always Finley: Converted custom Figma mockups into responsive Shopify 2.0 sections so internal teams edit campaigns directly in the Theme Editor without touching code. - Lucky Ducks & Island Kine Snacks: Re-engineered custom Dawn mega-menus, product page layouts, and Core Web Vitals for faster mobile checkout. Core Engineering Scope: - Figma to Pixel-Perfect Shopify OS 2.0 Themes (JSON templates, modular sections & blocks) - Custom Liquid, Vanilla JavaScript (ES6+), HTML5, and CSS3 (zero PageFly/Shogun bloat) - High-Converting PDPs, Custom Bundle Builders, Sticky ATC & Slide-Out AJAX Cart Drawers - Core Web Vitals & Mobile Speed Optimization (script deferral, asset pruning, sub-2s load) - Complex Metafields, Metaobjects & Storefront/Admin API Integrations - Safe Git + Shopify CLI Staging Workflows (zero downtime on live stores) See live case studies in my Portfolio section below, or send over your store details and Figma mockup - I will reply with a clear plan, timeline, and honest estimate.
