About this gig

Ive always been interested in what happens behind the surface as why something works, why it doesnt and what can be done to make it work better. That mindset has shaped the way I approach Shopify: understand the problem first, then find the most practical solution. I work with Shopify Liquid, HTML, CSS and JavaScript to fix bugs, customize themes and develop specific storefront functionality. Whether it is a small theme error or a more involved customization, I pay close attention to how the change affects the rest of the store. I prefer clean implementation, responsive behaviour and solutions that improve the store without introducing unnecessary complexity. If something in your Shopify store isnt working as it should, tell me what youre seeing and Ill take a closer look.


Tools I Use:

  • Shopify CLI
  • Liquid 
  • HTML & CSS 
  • JavaScript
  • JSON
  • Theme Check


How I Think:

  • What is failing
  • Why it is happening
  • What depends on it


What I Will Fix or Build:

  • I can repair existing theme code  
  • Customize sections and blocks  
  • Create Liquid functionality  
  • Adjust HTML/CSS/JavaScript  
  • Improve theme settings 
  • Storefront behaviour


Tell me what is not working and Ill check the best way to solve it.
