Senior Shopify Front-End Developer – Migrate Existing Quiz UI to Shopify

We are looking for an experienced Shopify front-end developer to migrate the frontend of our existing supplement recommendation quiz into our Shopify store: vitruvin.com.

The quiz is currently built with React/Next.js and hosted on Vercel. We want only the customer-facing frontend moved to Shopify. The existing backend, APIs, quiz logic and Supabase database should remain as they are.

Current: Shopify → separate Vercel quiz frontend → Backend/API → Supabase

Target: Shopify quiz frontend → existing Backend/API → Supabase

The entire customer experience should remain on vitruvin.com, ideally /quiz.

Scope Rebuild existing Figma quiz design inside Shopify Shopify Liquid + HTML/CSS + JavaScript Fully responsive and pixel-accurate Create clean, reusable quiz components Connect Shopify frontend to existing backend/API Preserve existing quiz logic, results and Supabase functionality Preserve quiz drop-off/event tracking, Meta Pixel and GA4 Shopify product recommendations + Add to Cart Clean, maintainable code stored in our GitHub No backend rebuild required Required experience

Strong experience with:

Shopify / Liquid / JavaScript / HTML/CSS / API integrations / GitHub

You should also be comfortable understanding existing React/Next.js, Vercel and Supabase code.

When applying, please provide 2–3 relevant Shopify projects, preferably including a quiz, product finder, configurator or other custom interactive functionality.

Please do not apply if your Shopify experience is mainly page builders or app installation. We need a developer experienced with custom Shopify development.
