I will fix one reproducible python or javascript bug


About this gig
Have one reproducible Python or JavaScript bug blocking your project?
Send the relevant code or repository, the error message, and what you expected to happen.
I will:
- identify the root cause
- make the smallest safe fix
- avoid unrelated rewrites
- run the relevant test or verification when the environment allows it
- return the patch with a concise explanation
Best for:
- exceptions and stack traces
- failing tests
- broken API endpoints
- import or dependency issues
- frontend JavaScript bugs
- regressions after a code change
Basic package covers one clearly reproducible bug.
No meeting or call is required. Everything can be handled through Fiverr messages and files.

FAQ
Do I need to join a call?
No. The service is designed to be completed through Fiverr messages and files.
What counts as one bug?
One reproducible defect with one primary root cause. If the issue turns out to contain multiple unrelated defects, I will tell you before doing additional work.
Can you work from a GitHub repository?
Yes, if the buyer can provide the repository or relevant files through an allowed Fiverr workflow.
What if the bug cannot be reproduced?
I will report what blocks reproduction and the exact information needed next rather than pretending the issue is fixed.
