About this gig

Struggling with critical Next.js & Headless Shopify bugs that hurt your Google SEO and sales? Most developers fail at optimizing the React engine under heavy traffic. 


I am an Expert E-commerce Developer specializing in resolving advanced architectural bugs within Custom Next.js & Headless Shopify storefronts. Watch my portfolio video on this gig to see my exact solutions in action!


Here is what I solve for your store:


1. NEXT.JS HYDRATION RECOVERY

I eliminate server-client rendering mismatches entirely by implementing clean, two-pass rendering (isMounted) shields, ensuring your storefront loads instantly without red screens.


2. CART RACE CONDITIONS FIXED

I stop rapid-click sabotages and cart freezing issues. By building robust Optimistic UI Updates, your Add-to-Cart buttons will execute smoothly with zero interface lag.


3. REAL-TIME STOCK & CACHE SYNC 

I build custom inventory revalidation engines that prevent stale product data during aggressive flash sales, syncing your real-time Shopify backend inventory.


Send me a message with your store link, and let's optimize your Next.js application!
