Über diesen Service

Is your JavaScript, React, or Node.js application not working properly?



Dealing with errors, broken features, failed API requests, or unexpected behavior? I can help you find the root cause and get your application working again.

I can fix:

  • JavaScript and React bugs
  • Node.js and Express backend issues
  • REST API and integration problems
  • Authentication and authorization errors
  • Database and backend issues
  • Console and runtime errors
  • State management problems
  • Performance issues
  • Code that needs refactoring


I don't just patch the visible error. I'll investigate the problem, identify the cause, implement the fix, and test the affected functionality.


Whether it's a small JavaScript bug, broken React component, failing API, or Node.js backend issue, I'll help get your project back on track.


Send me the error message, screenshot, or relevant code, and let's find the problem.
