About this gig

If your application has bugs, errors, or unexpected behavior I can help you fix them quickly and reliably.


I specialize in debugging and fixing issues in React, Next.js, and Node.js applications. I carefully analyze your codebase, identify the root cause of the problem, and provide a clean, stable solution without breaking existing functionality.


I work with both frontend and backend issues, including logic errors, broken UI behavior, API problems, runtime errors, and performance-related bugs. My goal is not just to apply a quick patch, but to fix issues properly so they dont return later.


In addition to bug fixing, I can also help with UI improvements and small redesigns based on your existing design. I dont create designs from scratch, but I confidently work with current layouts, components, and styles to improve usability, consistency, and visual clarity.


Youll get:

  • Careful bug investigation
  • A tested and reliable fix
  • Clean, maintainable code
  • UI refinements when needed
  • Clear and honest communication


If youre not sure whats causing the issue thats totally fine. I can investigate it for you.
