To design and implement a high-performance Shopify storefront for an electronics retailer that sells device accessories and consumer electronics. The goal was to create a fast, mobile-first shopping experience that handles many SKUs and variants, makes it simple for customers to find device-compatible products, and supports merchant workflows for inventory, shipping, and promotions.

Large product catalog with many device-specific variants (models, colors, materials) that required clear filtering and easy discovery.

High expectations for product presentation: large images, technical specs, and trust signals (reviews, warranties).

Mobile traffic dominance — the theme needed to be extremely fast and usable on phones.

Need to integrate multiple third-party services (email marketing, reviews, subscription/bundles, shipping/fulfillment) while keeping the checkout flow frictionless.

Merchant wanted enough admin flexibility to manage variants, promotions, and content without developer changes.

Delivered a custom Shopify implementation that balanced polish, performance, and merchant control. Key decisions and implementations included:

Shopify theme development using Liquid, modular Sections/Blocks, and a componentized approach for reusability.

Local development workflow with Shopify CLI, Git source control, and build tooling (Node.js + npm scripts / webpack or equivalent bundler).

Use of Shopify Storefront API or REST Admin API (where needed) for custom storefront widgets and headless components.

Built a pixel-perfect responsive theme (mobile-first) with:

Custom homepage components (hero, feature strips, category highlights).

Product detail templates that surface technical specifications, compatibility selector (“Select your device”), and clear badges for features (e.g., wireless charging, shock protection).

High-quality image galleries with lazy loading and WebP fallbacks.

Custom cart drawer and sticky “Add to cart” with quantity & variant picker.

Implemented section-based components so merchant could edit content in Shopify’s theme editor without dev changes.

Designed a scalable product model using product variants + metafields for technical specs, compatibility lists, and extra content blocks.

Implemented device compatibility filters (e.g., pick model → show only compatible cases).

Created an intuitive collection & faceted filtering UI (category, material, price, features).

Implemented dynamic discounts, free-shipping thresholds, and upsell/cross-sell blocks on PDP and cart.

If Shopify Plus was available: delivered scriptable discounts and checkout customizations; otherwise implemented app-based workarounds and post-purchase upsells.

Built product bundles and subscription options (using a subscriptions app integration) where required.

Payments: configured Shopify Payments & fallback gateways.

Fulfillment & shipping: connected to fulfillment apps (ShipStation / carrier tools) for real-time shipping rates and label generation.

Analytics: GA4 + Google Tag Manager and events for AddToCart, CheckoutStart, Purchase for conversion tracking.
