FAQ
Do I need to contact you before placing an order?
Yes. Please contact me before ordering and describe the issue, expected behavior, error messages, and steps to reproduce the bug. I will review the information and recommend the appropriate package.
What information do you need to investigate the bug?
I need a clear description of the issue, steps to reproduce it, expected and actual behavior, error messages or logs, relevant screenshots, and access to the source code or development environment when required.
Can you guarantee that every bug can be fixed?
I will investigate the issue and work toward a reliable solution. However, some problems may depend on unavailable source code, third-party services, infrastructure, external APIs, or issues outside the agreed scope. Please contact me before ordering so I can evaluate the problem.
Does this Gig include new features or application development?
No. This Gig is focused on investigating and fixing bugs in existing applications. New features, major refactoring, application rewrites, and large architectural changes require a separate agreement or custom offer.
What happens if you discover additional unrelated bugs?
I will report any additional issues I discover. Unrelated bugs are not automatically included in the original order and can be handled through another package, an extra service, or a custom offer after we agree on the scope.
