ZIP file (React/JS site) into a Shopify-compatible theme.(ZIP Provided)

I have a fully designed website built using ReactJS (with JavaScript and minimal backend). The entire website is available in a ZIP file, including all frontend assets and layout.

I want to replicate this design and layout as a custom Shopify theme.

- This is not about integrating React with Shopify — I want the same design recreated using Shopify's Liquid templating system, HTML, CSS, and JavaScript to work natively as a Shopify theme.

The site was never launched and has no eCommerce backend. I prefer to use Shopify for ease of management and future scalability.

* Key Responsibilities:
- Analyze the existing ReactJS site design (provided via ZIP)

- Recreate the same UI/UX using Shopify's theme structure

- Use Shopify's Liquid, HTML, CSS, JS

- Ensure theme is fully responsive (mobile/tablet/desktop)

- Implement basic Shopify sections (homepage, product page, collections, etc.)

- Set up a clean, editable theme with proper Shopify admin compatibility

- Add support for discount coupon entry at checkout (can leave logic placeholder)
