Why Haystack
The fastest way to hire .NET developers - without the agency tax.
.NET is the default for a huge share of enterprise back-ends - financial services, public sector, ISVs. With .NET 8 the platform is faster than ever, but real production work still requires people who can navigate legacy Framework code and modernise it incrementally.
Haystack's .NET pool spans ASP.NET Core, Blazor, MAUI and the older Framework. We surface the runtime version, the testing approach and the team's deployment target on every profile.
What they ship
Production .NET work, not tutorials.
- ASP.NET Core minimal APIs and gRPC services on Linux containers
- Blazor Server / WebAssembly internal apps
- Background workers with Hangfire, MassTransit or Azure Functions
- Modernisations from .NET Framework 4.x to .NET 8
