csharp-developer
Build REST APIs, Blazor apps, and cloud-native solutions with .NET 8+ and modern C# patterns.
- Implements ASP.NET Core APIs using Minimal or Controller-based routing, with Entity Framework Core for data access and async/await throughout
- Structures applications with CQRS via MediatR, dependency injection, and strongly-typed configuration
- Enforces nullable reference types, cancellation tokens, Result pattern error handling, and DTO mapping to prevent EF entity leakage
- Scaffolds Blazor components (Server/WASM) with state management and includes xUnit testing with 80%+ coverage targets
- Applies performance optimization using Span, Memory, and async patterns; includes EF Core migration checkpoints before applying schema changes
