About this gig

Is your Shopify store live but not performing the way it should?

Slow load times, broken sections, a theme that doesn't match your brand, layout issues on mobile, or apps clashing with each other these problems silently kill your conversions every single day. The good news: they're all fixable.


I specialize in Shopify store fixes and optimization for existing stores. Whether you have one specific issue or need a full store audit and cleanup, I dig into the code, find what's broken or underperforming, and fix it properly.


What I Fix & Optimize

  1. Shopify Speed Optimization
  2. Liquid Code Customization
  3. Mobile Responsiveness Fixes
  4. App Conflict Resolution
  5. Layout & Section Repairs
  6. Theme Customization
  7. Conversion Optimization
  8. Custom CSS & JavaScript
  9. Checkout Page Customization
  10. Store Performance Audit


My Process Simple & Safe

1.   Share your store URL and a brief description of the issue(s)

2.   I audit your store and identify the root cause

3.   I provide a fix plan and get your approval before making changes

4.   I implement the fixes directly in your store (or via a duplicate theme for safety)

5.   You review the changes I deliver a before/after performance report
