FAQ
Q1 — What information do you need to fix my bug?
I need access to your code (GitHub repo or ZIP file) and the following details: • A short description of the bug • Any error messages from the console or terminal • Steps to reproduce the issue (if possible) The more details you provide, the faster I can diagnose and fix the problem.
Q2 — What if you can't fix my bug?
If I accept your order and the issue cannot be resolved within the agreed scope, I will inform you immediately and offer a full refund. To avoid this, please message me before ordering with a short description of your issue.
Q3 — Do you fix bugs in large or complex projects?
Yes. However, large codebases may require the Standard or Premium package due to the time needed to analyze the project. If your project is complex, send me a message first and I will recommend the right package.
Q4 — Will you explain what caused the bug?
Yes. Every delivery includes a clear explanation of: • The root cause of the issue • What changes were made • Suggestions to prevent similar problems in the future

Yes. I understand many projects are private or pre-launch. I’m happy to sign an NDA before accessing your code. Just message me before ordering if this is required.

Basic: 1 revision Standard: 2 revisions Premium: 3 revisions Revisions apply if the original issue isn't fully resolved. New features or unrelated bugs are not included.
