About this gig

Need help fixing, improving, or extending an existing .NET MAUI application?

I'm a senior C#/.NET developer and independent consultant running Microtechnics.

I help businesses maintain and extend existing .NET MAUI applications, with a primary focus on Android.

What I can help with:

  • Fixing bugs and crashes
  • Implementing new screens and features
  • REST API integration
  • Improving application performance
  • Refactoring existing C# and XAML code
  • Troubleshooting Android build and deployment issues
  • Modernizing existing Xamarin or .NET MAUI components

How I work

Each project is based on a clearly defined scope and agreed deliverables.

Before implementation, I review your requirements and confirm what can realistically be delivered.

Important

Android is my primary supported platform.

iOS-related work depends on the availability of a suitable Apple build environment, certificates, provisioning profiles, and signing configuration. iOS builds and publishing are not included unless explicitly agreed.

Please contact me before ordering so we can confirm the scope and select the right package.
