FAQ
What information do you need to start fixing my bug?
I will need temporary access to your website's codebase (cPanel, FTP, GitHub, or live credentials) and a detailed description or screenshot/video of the issue you are facing.
Can you fix complex JavaScript or React.js bugs?
Yes! I have deep expertise in modern JavaScript (ES6+) and frameworks like React. I can trace code execution, identify logic flaws, and fix state management or API-related bugs seamlessly.
Will fixing the bug affect other parts of my website?
No. I write clean, modular, and isolated code fixes to ensure that resolving one issue will not create new problems elsewhere on your site.
Do you offer urgent or emergency bug-fixing services?
Absolutely. If you have a critical bug that needs immediate attention, please send me a message first, and I will prioritize your request.
