FAQ
How quickly can you fix my website or app bug?
Most UI, styling, and standard React or Next.js bugs are resolved within 12 to 24 hours. For urgent issues, please send me a message for priority delivery.
Do you fix both frontend and backend bugs?
Yes! I am a full-stack developer experienced in fixing React, Next.js, JavaScript frontend issues as well as Node.js, Express, and database API errors on the backend.
What information or access do you need from me to start?
I need a brief explanation of the bug, screenshots or video clips of the error, and temporary access to your source code (GitHub, Vercel, cPanel, or live site credentials).
Will fixing this bug break other features on my site?
No. I inspect the entire codebase and test thoroughly after applying the fix to ensure your existing layout and logic remain completely untouched and stable.
What if my issue is complex or involves multiple bugs?
Please message me directly before ordering! I will evaluate your system, analyze the root cause, and send you a transparent custom offer tailored to your project scope.
