About this gig
Have a Python script or application that crashes, throws an error, produces incorrect results, or simply stopped working?
I can debug your existing Python code, identify the cause, and fix the problem.
Typical issues include:
- exceptions and tracebacks
- incorrect output or logic errors
- broken file/data processing
- import or dependency problems
- API/request errors in existing code
- pandas/data handling bugs
- loops, conditions and function errors
- small compatibility issues
- code that stopped working after a change
Basic: one specific, reproducible bug or error.
Standard: one more complex issue or several closely related bugs in the same project.
Premium: bug fixing plus targeted cleanup/refactoring and basic tests where appropriate.
Fixed packages are for debugging existing code. New features, major refactoring, deployment/server issues, architecture changes, or large projects require a custom offer.
I have 15 years of professional software development experience and hundreds of completed Fiverr orders.

FAQ
What is included in the Basic package?
One specific, reproducible bug or error in existing Python code. I will diagnose the cause, fix it, verify the reported issue, and return the updated source code.
Can you fix several bugs?
Yes, if they are closely related. Several unrelated issues may require Standard, Premium, or a custom offer depending on their complexity.
What do you need from me?
Please provide the source code, the error message or incorrect behavior, and clear steps to reproduce the problem.
Can you fix code that does not show an error message?
Yes. Incorrect output, unexpected behavior, logic problems, and code that silently fails can also be debugged.
Can you fix pandas, API or data-processing code?
Yes. I regularly work with Python data processing, pandas, files, APIs, JSON, CSV, Excel and similar workflows.
Will you add new features?
Not as part of the fixed bug-fixing packages. Small changes may be possible, but feature development should be discussed separately.
Can you debug a large existing application?
Possibly, but please contact me first. Large or unfamiliar projects can require significant investigation and may need a custom offer.
Do you provide the fixed source code?
Yes. All packages include the modified Python source code for the agreed bug fix.
