I will build headless shopify store with hydrogen and next js

I build headless Shopify stores using the Storefront API, Shopify Hydrogen, or a custom Next.js frontend for stores that have outgrown the built-in theme system. As Shopify stores scale, the built-in storefront often becomes the bottleneck slow, hard to customize, limited in what it can do and headless commerce gives you full control over performance and features while keeping Shopify's backend for inventory, orders, and payments.

I can help with:

• Shopify Storefront/Admin API integration
• Headless architecture design (Next.js frontend + Shopify or custom backend)
• Custom checkout logic and third-party service integration
• Migrating specific store logic to a custom backend when Shopify's limits become a problem

This is for stores that have outgrown template-based Shopify setups, not first-time store owners.
