Web Development for E-Commerce — Lighthouse-92+ Storefronts
E-commerce web is where conversion either compounds or leaks. We rebuild legacy storefronts on Next.js with edge CDN, optimised image pipelines and one-page mobile checkout — the work that took StyleNow from Lighthouse 42 to 94.
The problem
Legacy stacks (Magento, WooCommerce, older Shopify themes) routinely Lighthouse-score in the 40s on mobile. That's a conversion problem before it's a Google ranking problem. We rebuild the front-of-funnel and migrate the back-office gradually.
Our approach
Headless Next.js migration
Keep Shopify / BigCommerce / Magento as the back-office. Rebuild the storefront on Next.js 14 with App Router, RSC streaming and ISR.
Image and asset pipeline rebuilt
Next.js Image with edge CDN, AVIF/WebP, automatic responsive sizes and lazy loading. Product images that weighed 800 KB ship at 80 KB.
One-page mobile-first checkout
Smart defaults, address autocomplete, stored payments, abandoned-cart recovery — the metric we move is mobile conversion, not desktop AOV.
