About this gig

Shopify stores can lose sales when the theme looks outdated, custom features dont work properly, bugs affect the shopping experience, or poor performance hurts SEO. I help Shopify store owners fix these issues and turn their existing store into a faster, cleaner, and more functional shopping experience.


As a Shopify Expert and Theme Developer, I can help with:

  • Shopify theme customization & development
  • Custom Liquid, HTML, CSS & JavaScript coding
  • Shopify bug fixing and troubleshooting
  • Custom sections, pages, menus, popups & product features
  • Homepage, product, collection, cart & header/footer customization
  • Mobile responsive design improvements
  • Shopify speed & performance optimization
  • Shopify technical SEO optimization
  • On-page SEO improvements
  • Third-party app integration


Whether you need a small theme adjustment, a complex custom feature, a stubborn bug fixed, or your store optimized for better performance and search visibility, I focus on clean implementation and solutions that fit your store.


Please contact me before placing an order so I can review your requirements and recommend the right approach. Custom projects may require different pricing depending on complexity.
