Sanity CMS Expert for Headless Ecommerce Build (Astro 5 + Shopify + Vercel)

We are building a headless ecommerce site for a supplements brand. The tech stack is Astro 5, Sanity CMS, headless Shopify, and Vercel. We need a Sanity expert to own the content layer end to end. This includes schema design, custom document types, GROQ queries, Sanity Studio configuration, and clean integration with our Astro 5 frontend. The project is already in an active architecture sprint, so we need someone who can hit the ground running with minimal hand-holding. What we need from you: Sanity v3 schema design and studio customisation, GROQ queries for product and content pages, headless Shopify integration via Sanity (or alongside it), Vercel deployment experience, and clean handoff documentation. You are a great fit if: You have shipped at least one headless ecommerce project using Sanity, you are comfortable working async with a remote team, and you communicate clearly in writing. Engagement: Fixed price or hourly, open to discussion based on your approach.
