FAQ
What do you need from me to start?
Your error message, stack trace (if available), and a short description of the issue. Source code access is required to fix it.
Do you work on existing code only?
Yes. I debug and repair your current WinForms or WPF application, no rewrites unless you request one.
Can you fix SQL Server connection issues?
Yes. I repair connectivity, data access, and query errors between your .NET app & SQL Server.
How fast is delivery?
Most single bugs are fixed within 1–2 days. If complex or multiple bugs may take longer, I'll confirm before you order.
What if the bug can't be reproduced?
I'll request logs or steps to reproduce. If it can't be diagnosed, you won't be charged for the failed attempt.
Will my code stay confidential?
Yes. I sign an NDA on request and never share or reuse your code.
Do you provide a report of the fix?
Yes. Every order includes a root cause explanation, the fix applied, and a testing summary.
Can you fix multiple bugs in one order?
Yes. Choose the Standard or Complete package for multiple fixes. Message me first for a scope confirmation.
