About this gig

Need a C# library, utility class, NuGet package, or internal developer tool? I build clean, reusable, well-documented .NET components that integrate seamlessly into your existing codebase.

What I can build:

Helper and utility libraries (string, date, file, HTTP helpers)

Data access layers and repository pattern implementations

API client wrappers for third-party services

Custom middleware for ASP.NET Core pipelines

CLI tools using System.CommandLine or Spectre.Console

Background services and hosted worker libraries

NuGet-ready packages with proper versioning


Delivery includes:

Full source code clean, SOLID, and commented

XML documentation on all public APIs

Unit tests (NUnit/xUnit) for core logic

README with usage examples
