FAQ
Do I need to share my full codebase?
Only the relevant files or repository access needed to investigate the bug. You don't need to share the entire project if the issue is isolated.
What if the bug takes longer to fix than expected?
I'll always investigate first and confirm scope before starting. If the issue turns out to be more complex, I'll let you know and adjust the package or timeline before proceeding.
Do you fix bugs in any Go framework?
I primarily work with Go's standard net/http and common patterns like Gin, but I can review other frameworks too — share your code and I'll confirm.
Will you explain what caused the bug?
Yes, I provide a clear explanation of the root cause and the fix applied, so you understand what went wrong.
Can you fix multiple bugs in one order?
The Basic package covers a single small bug. For multiple issues, please choose the Standard or Premium package based on scope.
Do you offer support after the fix is delivered?
Yes, I offer revisions as per the selected package and I'm available for quick follow-up questions after delivery.
