I develop and modernise cross-platform desktop applications using C#, .NET, Avalonia UI, XAML, and MVVM. This service is suitable for businesses that need one maintainable application across Windows, macOS, and Linux, or want to migrate an existing WPF application to a modern cross-platform solution.

I can help with:

• New desktop applications and internal business tools • WPF-to-Avalonia migration and modernisation • MVVM architecture and reusable UI components • REST API, SQLite, and external-system integration • Debugging, performance improvements, and refactoring • Packaging and deployment for supported platforms

Before development begins, we will agree on the target platforms, requirements, deliverables, and milestones. You will receive maintainable source code, documentation, and a solution designed around your actual workflow.
