Hire C# / .NET Developers

C# is the programming language; .NET is the runtime and framework ecosystem. In practice, the terms are used interchangeably — all Kultrix .NET developers write C# and work across the full .NET stack including ASP.NET Core, Entity Framework, and the Azure SDK. When we say C# developer, we mean someone fluent in the complete Microsoft backend platform.

Most Kultrix engagements begin within 48 hours of contract signing. We maintain a bench of vetted senior .NET developers available for immediate placement. For larger teams or highly specialised requirements such as Blazor or Azure Service Fabric, a one-week lead time is typical.

Yes — joining a live codebase is standard practice for Kultrix developers. They begin with a code review, map dependencies, identify technical debt, and align with your architecture before writing their first PR. Productive contribution typically begins within the first sprint.

Absolutely. We have completed multiple .NET Framework to .NET 8 migrations, including projects using Web Forms, WCF, and ASMX web services. We assess compatibility, prioritise the migration path, automate what can be automated, and rewrite what cannot be safely ported. Migrations are done incrementally to minimise delivery risk.

Our .NET developers are fluent across Azure App Service, Azure Functions, Azure Service Bus, Azure SQL, Cosmos DB, Blob Storage, AKS, and Azure DevOps pipelines. We apply Managed Identity throughout to eliminate hard-coded secrets, and use Key Vault for configuration management.

Testing is not optional at Kultrix. Our developers write xUnit tests for business logic, use Moq or NSubstitute for mocking, and set up integration tests against a real database using TestContainers. Coverage gates are configured in CI so regressions are caught before they reach production.

Yes. Fixed-scope engagements such as building an API, migrating a database, or implementing a payment integration are scoped after a discovery call and quoted with a fixed price and timeline. Changes are handled through a straightforward change-order process that keeps delivery on track.

All Kultrix .NET developers are mid-to-senior level with a minimum of four years of professional C# experience. Every developer passes a technical interview covering OOP design, async patterns, and SQL before joining our bench. We do not place juniors on client engagements.

We offer monthly retainer and time-and-materials models. Retainer engagements include a fixed allocation of developer hours with a guaranteed response SLA. T&M engagements are billed weekly against tracked hours. Both models include transparent timesheets and a dedicated account manager.

Yes. Kultrix developers structure .NET projects using clean or onion architecture, separating domain, application, infrastructure, and presentation concerns. This makes the codebase easier to test, easier to extend, and easier for new team members to navigate from day one.

Yes. We have experience with both Blazor Server and Blazor WebAssembly, including authentication with MSAL, state management with Fluxor, and publishing optimised WASM bundles. If your team wants to avoid a JavaScript frontend while keeping rich interactivity, Blazor WebAssembly is a strong choice and we can lead that implementation.

Kultrix is a product-focused agency, not a talent marketplace. Every developer is a Kultrix employee or long-term contractor — not an anonymous profile. We manage quality, handle replacements if a fit is not working, and provide a dedicated account manager. You get the flexibility of a freelancer with the accountability of an agency.
