Shopify Developer for Variant UX & Image Switching Fixes

I need an experienced Shopify developer to fix product variant functionality and resolve UX issues on my e-commerce site.

The main issues that need to be addressed:
- Ensure all products have working color variants
- Enable automatic image switching when customers select different variants
- Fix page jump/scroll issue that occurs when selecting variants
- Review and resolve UI/UX bugs across all product pages

Requirements:
- Strong experience with Shopify development (Liquid templating and themes)
- Proven ability to troubleshoot frontend UX issues
- Detail-oriented approach to clean e-commerce execution
- Available to start immediately

Deliverables:
- Fully functional color variants across all products
- Smooth image switching functionality based on variant selection
- Elimination of page jumping/scrolling issues
- Clean, bug-free UI across product pages
- Brief documentation of changes made

This is a one-time project with potential for ongoing work if the results are excellent. I have a video demonstration of the issues and an Excel sheet with the product list that I'll share with the selected developer.

Looking for someone who can deliver quality work quickly and has experience with similar Shopify variant and UX optimization projects.
