I need a fully custom Shopify theme built based on existing websites/ideas. Here’s what I’m after: • Custom Liquid templates and sections for the home page, collection pages, product detail pages, cart, and a lightweight, distraction-free checkout style • Responsive CSS that looks sharp on mobile first but scales beautifully on tablets and desktops • Modern UI touches—subtle micro-interactions, smooth transitions, and a design system that aligns with the brand’s color palette and typography • Clean, commented code so I’m not locked out of future tweaks • Basic performance optimisation (lazy loading, compressed assets) and SEO-friendly markup Acceptance criteria: 1. Theme uploads without errors and passes Shopify’s Theme Check. 2. All core templates render properly using sample data. 3. PageSpeed Insights scores 85+ on mobile for the default demo. 4. Written hand-off guide covering theme settings, section usage, and asset replacement. 5. Complete support of Shopify native logics If you’ve designed modern Shopify themes before—especially for physical products—let’s collaborate and make this store stand out.
