Core Technical Skills & Architecture

Mandatory Expertise

The developer must possess strong expertise in:

• C# and modern .NET: Utilizing the latest features of the language and framework.
• Avalonia UI: For cross-platform UI development.
• MVVM Architecture: Maintaining strict separation between UI and business logic.
• Clean Code & Clean Architecture: Focusing on maintainability and inward dependency flow.
• Functional Programming in C#: Embracing immutability and functional patterns.
• Reactive Programming: Expertise in DynamicData and System.Reactive.

Architectural Principles

• Pure MVVM: Mandatory for all UI code. Logic must be independent of UI concerns.
• Composition over Inheritance: Favor modular building blocks over deep inheritance hierarchies.
• Inward Dependency Flow: Abstractions must not depend on implementations.
• Immutability: Prefer immutable structures where practical to ensure predictability.
• Stable Public APIs: Design APIs carefully to ensure long-term stability and clarity.
