The Challenge: The Speed Tax on Revenue
Our client, a mid-sized specialty retailer, was losing significant revenue due to a legacy e-commerce platform built on outdated technology. Their average mobile page load time was over 4.5 seconds, resulting in a 40%+ mobile bounce rate. Their primary business challenge was that poor performance was acting as a “speed tax” on every transaction. The existing architecture was monolithic, difficult to deploy, and impossible to optimize for modern Core Web Vitals standards.
DevoxLabs' Full-Stack Solution
We implemented a complete full-stack transformation focused on performance-first engineering:
Next.js Storefront: Built a new, lean frontend utilizing Next.js, leveraging Static Site Generation (SSG) for static pages and Incremental Static Regeneration (ISR) for frequently updated product pages, ensuring content was always served from the edge cache.
API Decoupling: Decoupled the monolithic application into a series of lightweight, GraphQL-based microservices, ensuring only necessary data was fetched and minimizing latency.
Core Web Vitals Optimization: Implemented strict performance budgets during development, focusing on critical metrics such as Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
