I will fix, update, or maintain your legacy winforms or wpf application

Inherited a Windows desktop app that nobody understands? I can help.

Maybe the original developer retired or left. Maybe the app broke after a Windows update. Maybe you need one more feature, but no one on your team touches C# desktop code anymore.

I'm a US-based .NET engineer with deep experience in WinForms and WPF, the frameworks most freelancers have moved on from. I specialize in rescuing and maintaining legacy Windows applications that businesses still depend on every day.

What I can do for you:

• Diagnose and fix bugs in undocumented legacy code
• Add new features to existing WinForms/WPF applications
• Fix crashes after Windows or .NET updates
• Connect your desktop app to modern APIs, databases, or web services
• Upgrade old .NET Framework projects to newer versions
• Document your codebase, so you're never stranded again

Why work with me:

• Native English, US time zone, clear communication, real availability
• I read legacy code for a living; no codebase scares me
• Fixed-scope quotes, no surprise costs
• Clean, commented code and documentation with every delivery
