A conversion-optimized storefront engineered from scratch with a filterable product catalog, real-time inventory sync, persistent cart across sessions, and a serverless checkout pipeline — designed to handle thousands of concurrent purchase flows without a single point of failure.
The client had an existing WooCommerce store with a 68% cart abandonment rate, 4.2s load times on mobile, and no analytics beyond basic Google Analytics events. They needed a complete rebuild engineered for conversion and speed — without the overhead of a monolithic CMS.
Mobile cart abandonment was at 68% due to 4+ second load times on 3G connections. Every 100ms of latency was costing estimated $2,400/month in revenue.
Built with vanilla JS + CSS, no framework overhead. Lazy-loaded all product images, pre-cached critical CSS, and served via CDN — reducing FCP to 340ms on 3G.
Client required a frictionless checkout that didn't redirect to external payment gateways, to prevent trust drop-off on the payment step.
Implemented embedded Razorpay checkout modal with serverless Cloud Function webhook validation, keeping users fully on-site through the entire purchase journey.
A lightweight serverless architecture with a static frontend, edge-cached product catalog, and Firebase Cloud Functions handling all transactional operations — giving the speed of a static site with the dynamic power of a full backend.
Client-side product filtering by category, price, and rating with zero page reload — sub-50ms response on all filter interactions.
Cart state persisted across browser sessions using LocalStorage with Firestore sync on checkout — zero lost carts due to refresh or tab close.
Real-time low-stock indicators and countdown timers for flash sale pricing — increased add-to-cart rate by 23%.
Touch-enabled image zoom gallery with lazy-loading WebP thumbnails. 60fps swipe animations with no external library.
Automatic order confirmation emails with PDF invoice via SendGrid + Cloud Functions triggered on successful Razorpay webhook.
Full GA4 Enhanced E-commerce tracking with view_item, add_to_cart, begin_checkout, and purchase events mapped to revenue funnels.
