FAQ
What types of Angular and React bugs can you fix?
I fix a wide range of Angular and React bugs including component errors, routing issues, lifecycle hook problems, state management bugs, TypeScript errors, API integration failures, CORS errors, broken UI layouts, and build or dependency conflicts. Message me with your issue and I will confirm befor
How fast can you fix my Angular or React bug?
Most single bugs are resolved within 24 hours. Complex issues involving multiple components, API layers, or build configuration may take longer. I will give you an honest time estimate after reviewing your code before you place the order.
Can you fix React hooks errors and state management issues?
Yes. I fix React hooks errors, incorrect useEffect dependencies, stale closures, Redux or Context API state issues, and unnecessary re-render problems. These are among the most common React bugs and I resolve them regularly.
Do you fix API integration bugs and CORS errors?
Yes. I fix REST API integration issues including CORS errors, failed HTTP requests, incorrect response handling, authentication errors (JWT/token issues), and Angular HttpClient or Axios configuration problems.
Can you fix AG Grid, PrimeNG, or Material UI component errors?
Yes. I have direct production experience with AG Grid, PrimeNG, Angular Material, and CoreUI. I fix rendering bugs, sorting and filtering issues, pagination errors, styling conflicts, and event handling problems in all of these UI libraries.
What do you need from me to get started?
Share your code via GitHub, GitLab, or a zip file — along with a description of the bug, the error message or screenshot, and steps to reproduce the issue. The more detail you provide, the faster I can diagnose and fix it.
Will you explain what caused the bug after fixing it?
Yes. Every delivery includes a clear explanation of the root cause, what was changed, and why — so you understand the fix and can avoid the same issue in future. Clean, commented code is included in Standard and Premium packages.
