About this gig

Is a JavaScript or Firebase bug stopping your web application from working correctly?


I will investigate and fix clearly defined issues in your existing web application.


I can help with:

  • JavaScript errors and broken functionality
  • Firebase Authentication and login issues
  • Cloud Firestore queries, reads, writes, and permissions
  • Firebase security-rule problems
  • HTML and CSS layout issues
  • Responsive-design bugs
  • Forms and validation errors
  • Browser compatibility issues
  • Firebase Hosting or GitHub Pages deployment problems


You will receive:

  • A tested and maintainable fix
  • Clear communication throughout the order
  • An explanation of the issue and solution
  • Documentation according to your selected package


This Gig covers existing projects built mainly with JavaScript, HTML, CSS, Bootstrap, and Firebase.


Please contact me before ordering with the error message, screenshots, project details, and expected result so I can confirm the correct package.


Never send passwords, recovery codes, private keys, or other sensitive credentials.
