E-Commerce Platform Performance Rescue

The Challenge

A fast-growing fashion e-commerce brand was losing €50K+ monthly to abandoned carts caused by slow page loads. Their Shopify Plus setup had been heavily customized by multiple agencies, resulting in 8-second average page loads and a checkout that crashed during flash sales. With €12M in annual GMV at stake, they needed emergency intervention.

Our Solution

We conducted a comprehensive performance audit and implemented a phased optimization plan. The frontend was rebuilt with Next.js for optimal Core Web Vitals, while backend operations were moved to serverless functions. We implemented intelligent caching, image optimization, and a CDN strategy. For flash sales, we designed a virtual queue system that gracefully handled traffic spikes.

Results Achieved

  • Page load time reduced from 8.1s to 1.4s (83% improvement)
  • Conversion rate increased from 1.8% to 3.4%
  • Flash sale capacity increased from 500 to 10,000 concurrent users
  • Cart abandonment reduced by 34%
  • Core Web Vitals achieved green scores across all metrics
  • Estimated €180K additional annual revenue from improvements

We'd tried three agencies before Cloudrix, and each made things worse. Within two weeks of starting, they'd already cut our load time in half. The flash sale that used to crash our site? Our last drop handled 8,000 concurrent users without a hiccup. The ROI on this project paid for itself in the first month.
