Retail Replatform Increased Checkout Completion

Executive Summary

"The client had slow product pages, fragmented checkout, and inconsistent mobile behavior causing high abandonment."

1
The client had slow product pages, fragmented checkout, and inconsistent mobile behavior causing high abandonment.

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.

1
29% increase in checkout completion rate within the first 60 days post-launch.
2
42% faster median product page load time (LCP improved from 2.4s to 1.2s).
3
Support tickets related to checkout friction reduced by 34% annually.
4
Mobile conversion rate increased by 22%, driven by the responsive glassmorphic UI.
5
Total cost of ownership (TCO) reduced by 15% due to lower server overhead and automated scaling.
