About this gig

Hey! Broken custom code can make a polished Squarespace site feel unreliable fast.


If your JavaScript stopped working, code injection is causing errors, custom CSS is breaking layouts, or a script conflict is affecting buttons, forms, menus, animations, or mobile behavior, I can help fix it cleanly.


I troubleshoot Squarespace JavaScript issues, custom code bugs, CSS errors, code injection problems, script conflicts, responsive code issues, and broken custom features.


You'll get:

  • Squarespace JavaScript troubleshooting
  • Custom CSS and HTML fixes
  • Code injection error repair
  • Script conflict diagnosis
  • Responsive code cleanup
  • Cross-device testing
  • Clear explanation of what was fixed


I work carefully around your existing design and only change what is needed, so your site stays stable and easy to manage.


If your Squarespace custom code is broken, inconsistent, or throwing errors, send me a message or place your order and Ill help get it working properly.

I was obsessed with breaking apart code blocks and fixing broken layouts as a kid.

I am a veteran developer and not new to solving technical web challenges, though I am fresh on this platform.
