E-commerce Platform Modernization
Migrated a legacy PHP e-commerce system to a modern Next.js architecture, dramatically improving performance and developer experience.
The Problem
A growing retail business was struggling with a legacy PHP monolith that couldn't handle traffic spikes during sales events. Page load times exceeded 8 seconds, mobile experience was poor, and the development team spent most of their time fighting technical debt.
Constraints
- •Zero downtime migration required—revenue couldn't stop
- •Existing inventory and order management systems had to be preserved
- •SEO rankings needed protection during migration
- •Timeline: 4 months to peak season
Our Approach
We implemented a strangler fig pattern, gradually replacing PHP pages with Next.js while maintaining the existing backend. Server-side rendering ensured SEO continuity. We set up a staging environment mirroring production traffic to validate performance before cutover.
Outcomes
- 70% reduction in page load time (8s → 2.4s)
- 45% improvement in mobile conversion rate
- 99.9% uptime maintained during 3-month migration
- Development velocity doubled post-migration
