Improved page load speed by 20%

The Problem

The legacy checkout system suffered from slow load times and complex state synchronization issues, leading to a high cart abandonment rate during high-traffic events.

The Solution

Re-architected the cart state management using Recoil for atomic updates and implemented optimistic UI updates. Utilized Next.js SRR for initial load speed and lazy-loaded non-critical components.

Impact & Results

Reduced page load time by 40%, improved checkout conversion rate by 15%, and successfully handled 3x peak traffic during product launches.
