Timeline
- 1
10-week rollout: 2 weeks audit, 3 weeks storefront build, 2 weeks checkout, 2 weeks migration, 1 week launch hardening.
Approach
- 1
Conducted a comprehensive technical audit of the legacy monolithic platform, identifying database bottlenecks and slow synchronous API calls.
- 2
Rebuilt the storefront using Next.js with Server-Side Rendering (SSR) and Incremental Static Regeneration (ISR) for near-instant page loads.
- 3
Implemented automated image optimization using edge computing to reduce payload sizes by 60% without visual degradation.
- 4
Streamlined the checkout flow from a 5-step process to a single-page interactive experience with real-time field validation.
- 5
Integrated a headless payment gateway to improve reliability and support localized payment methods across multiple regions.
- 6
Added detailed analytics instrumentation to monitor funnel drop-off at every keystroke in the checkout process.
Results
- 1
29% increase in checkout completion after flow simplification.
- 2
42% improvement in median product page load time.
- 3
34% reduction in checkout-related support tickets.
Cost Impact
- 1
Cost impact came from higher checkout completion, fewer support requests, and lower infrastructure overhead.
