Project Overview
Project Overview
Next.js Edge-rendered headless commerce architecture scaling 10M+ product SKUs with 200ms latency, dynamic personalized pricing, and AI-driven checkout conversion lift.
Codytics designed and developed ShopScale Headless Enterprise Commerce Engine, a high-performance E-commerce platform for ShopScale Global Retailers, delivering a comprehensive digital solution across Web Apps and Cloud & SaaS and AI & Automation.
ShopScale is an omnichannel international retailer operating across 32 regional storefronts with an extensive catalog exceeding 10 million active fashion and electronics inventory units.
Codytics delivered the full platform in 10 months, covering Web Application Development, AI & ML Solutions.
A legacy monolith retailer suffered from 4.5s load times, cart abandonment rates above 72%, and recurring database lockouts during Black Friday and Cyber Week sales spikes.
ShopScale Headless Enterprise Commerce Engine was engineered to address these gaps through a workflow-first approach. Codytics designed the platform to optimize the entire operational lifecycle from ingestion to delivery with clarity, resilience, and operational discipline.
The product had strong vision, but the software was slowing the business down.
A legacy monolith retailer suffered from 4.5s load times, cart abandonment rates above 72%, and recurring database lockouts during Black Friday and Cyber Week sales spikes.
Core ArchitectureMonolithic Database Bottlenecks
The legacy PHP/Magento monolith locked product tables during simultaneous flash-sale updates, creating cascading 504 gateway timeout failures.
User WorkflowSevere Mobile Cart Abandonment
Multi-second page transitions on mobile networks led to severe shopper drop-offs, costing an estimated $8M in uncompleted seasonal checkouts.
System PerformanceFragmented Multi-Region Catalog Sync
Syncing localized currencies, VAT tax rates, and inventory across 32 regional warehouses caused catalog discrepancies and overselling incidents.
The Solution
How Codytics solved these problems.
Re-engineered the storefront on Next.js Edge SSR, backed by Elasticsearch clusters, decoupled headless checkout endpoints, and predictive product ranking algorithms.
Solution 01•Sub-200ms TTFBEdge SSR & Global CDN Routing
