I will fix go golang backend rest API bugs
Md. Khairozzama
About this gig
Struggling with a bug in your Go (Golang) backend or REST API?
I specialize in debugging and fixing issues in Go-based backend systems from small errors to complex backend/API problems.
I can fix:
- Compile-time and runtime errors
- API endpoint bugs & broken routes
- Database connection & query issues (PostgreSQL/SQLx)
- Authentication & JWT-related bugs
- Middleware & routing issues
- Performance & memory issues
- Logic errors in business/service layer
- Concurrency & goroutine issues
My process:
- 1. Investigate the bug and identify the root cause
- 2. Apply a clean, tested fix following Go best practices
- 3. Explain what was wrong and how it was fixed
Send me your error logs, repo access, or a description of the issue, and I'll get back with a clear diagnosis before starting work.
Please contact me before ordering so I can confirm the scope and give you an accurate timeline.

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.
