Headless Shopify New Pages Build

I need an experienced headless Shopify specialist to create a set of new pages for my existing store. The back-end is already wired up; your focus is purely front-end. You’ll take approved Figma mock-ups (or recreate an equivalent layout if you prefer) and turn them into fast, responsive pages that pull data from Shopify via the Storefront API.

Key expectations
• Pixel-perfect rendering that matches our current brand styling
• Smooth product, collection and cart interactions, handled entirely on the front end
• Lighthouse scores in the green and no console warnings
• Clean, well-documented code pushed to a Git repository and a short hand-over note so my in-house team can maintain it

Please share a concise summary of your experience building headless Shopify or Hydrogen/Next.js storefronts. Links to live shops or repos where you owned the front-end work will help me shortlist quickly.
