Technical Audit & Refactoring

E-Commerce Optimization

Conducted an extensive technical audit for a major EU retailer, optimizing their frontend performance to achieve a 95+ Core Web Vitals score.

The Problem

A major European e-commerce retailer noticed a significant drop in conversion rates, which correlated with poor website performance. Their Core Web Vitals were failing across the board, particularly Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS).

The Audit & Execution

We performed a deep-dive technical audit of their React application.

Key Optimizations:

  1. Image Optimization: Migrated all product images to Next-Gen formats (WebP/AVIF) and implemented responsive srcset.
  2. Code Splitting: Introduced dynamic imports for heavy components that were rarely used above the fold.
  3. State Management Refactor: Replaced unnecessary Redux global state with localized React Context and React Query for better caching.

The Results

  • Core Web Vitals: Achieved a score of 95+ on both Mobile and Desktop Google PageSpeed Insights.
  • Conversion Rate: E-commerce conversion rate increased by 18% month-over-month following the deployment.
