About this gig

Do you have one reproducible bug in an existing Python, Flask, or Django application?


I will investigate one clearly defined issue, identify the root cause, implement a focused fix, and verify the result. Examples include:

an error triggered by a specific action

incorrect data validation or calculation

a broken form, view, API endpoint, or database operation

a small regression after a recent change


You will receive:

the corrected source code

a short explanation of the root cause

verification notes showing how the fix was checked

one revision for the agreed bug


Before I start, I will confirm the reproduction steps, expected behavior, environment, relevant logs, and the exact acceptance check. Please remove passwords, API keys, personal data, and confidential business data before sharing files.


This Gig covers one reproducible bug. It does not include large feature development, full application audits, security certification, payment-system changes, enterprise authentication, or unrelated issues discovered during the work. Larger requests can be split into separate paid phases.

I build practical tools that replace repetitive spreadsheet work. My work includes Python, Flask and Django internal apps, Excel and VBA automation, CSV validation and processing, API integrations, and clear handover documentation. I have built tools for scheduling, record consolidation, quotation creation, contract workflows, and reporting. I define the input, output, error handling, and acceptance check before development so the deliverable is clear. I work in Japanese and English. We can usually confirm scope through messages, with a short web meeting only when needed.
