You will get a diagnosis report for one Python or C# bug
Project details
Understand one bug in your Python or C# code before committing to a fix.
I investigate one clearly described failure in a script, application or API integration that can be examined in a test environment. We define the failing input, actual result and expected behavior, then I review the relevant code and attempt to reproduce the issue.
You receive a diagnosis report with the steps attempted, observed results and evidence behind the findings. If the evidence supports a cause, I explain it and outline a next step. If I cannot reproduce the issue or establish its cause, I identify the specific blockers and information needed to continue.
This covers diagnosis only. Code fixes, features, deployment, security audits and whole-codebase reviews are excluded. One revision clarifies or corrects the report for the same issue. Further work is quoted separately.
Please share a sanitized example before ordering so I can confirm scope and environment. AI assistance is used only with your agreement on tools and data access. I review the analysis against observed behavior. Do not share production credentials or sensitive data.

About Manuel
Senior Python & C# Developer | Automation, APIs & Bug Fixes
Zaragoza, Spain - 3:30 pm local time
I'm a senior programmer specializing in Python and C#. I offer:
- Scripts and automation, including CSV, JSON and Excel file processing.
- REST API integrations and improvements to existing applications.
- Bug diagnosis, focused fixes, regression tests and refactoring.
We start with your goal, sample inputs, expected results and test environment. I confirm the scope, price and timing before work starts. Deliverables can include source code or a patch, setup notes, test results and documented limitations.
My portfolio includes an AI-assisted synthetic Python timestamp-ordering demo with 9 passing reference tests. It uses no client code or data.
For one bug, my Project Catalog offers a diagnosis report for 50 USD, with 3-day delivery after receiving requirements and one revision. Fixes are quoted separately. My hourly rate is 30 USD.
I use AI assistance only with your agreement on permitted tools and data. I review and test generated changes. Fluent in English and Spanish.
Message me on Upwork with a sanitized example and the result you need. Please exclude credentials and sensitive data.
Steps for completing your project
After purchasing the project, send requirements so Manuel can start the project.
Delivery time starts when Manuel receives requirements from you.
Manuel works on your project following the steps below.
Revisions may occur after the delivery date.
Review the example and test environment
Review the supplied code, inputs and expected behavior. Set up the agreed test environment and identify missing information or access restrictions.
Reproduce and investigate the issue
Attempt the reported reproduction steps, inspect the relevant code and record actual results. Investigate possible causes using the available evidence and clearly label uncertainty.
