FAQ
Should I message you before ordering?
Yes. Please send the live URL, error details, and project access so I can confirm the issue and recommend the correct package.
What counts as one bug?
One bug is one reproducible issue with a single expected outcome. Related symptoms may be grouped after I review the code.
Do you fix backend issues too?
I can fix frontend integration and simple Node or Nest API issues. Larger backend work requires a custom offer after scope review.
Will I receive the updated source code?
Yes. I will deliver the corrected source code and a concise summary of the changes made and tests completed.
