FAQ
1. Do I need to provide source code?
Yes, I will need access to your source code or repository to review the codebase before starting. This lets me understand your current architecture, identify the root cause of the issue, and give you an accurate timeline. I can sign an NDA before reviewing any code if needed.
2: Can you fix bugs in an application built by another developer?
Yes, I regularly take over and maintain existing ASP.NET Web Forms applications. I will review the code, fix the issues, and deliver clean updates without requiring a full rewrite.
3: What .NET Framework versions do you work with?
I work with ASP.NET Web Forms on .NET Framework 4.0 through 4.8.1, using C# and SQL Server. If your application is running on an older or specific version, message me and I will confirm compatibility before you order.
4. What information do you need to start?
Please provide: (1) a brief description of the bug or feature, (2) your source code, and (3) the .NET Framework version your app uses.
5. What if my project needs more work than the package includes?
I will let you know before starting so we can adjust the package together. If it is larger than the Standard scope, I will recommend the Premium package or send a custom offer.
