.NET and C# engineers for backend and cloud applications

C# software engineers build and extend enterprise backends where business rules need to remain consistent across applications. ASP.NET Core development covers HTTP APIs and background processing, with clear boundaries between application logic and data access.

For database-heavy applications, engineers use Entity Framework Core or SQL directly to investigate query behaviour and implement transaction handling. Automated tests cover business rules and failure cases, so changes to pricing or approval workflows can be checked before release.

Connect .NET applications to business systems through documented interfaces and recoverable data flows. Integration engineers handle authentication and API versioning, including compatibility with existing consumers.

• REST and legacy interfaces: Build ASP.NET Core endpoints or adapt SOAP services to connect ERP and CRM applications. Define validation rules and map external data into application models.
• Event-driven integration: Implement asynchronous workflows with Azure Service Bus or RabbitMQ. Configure retries and dead-letter handling, with idempotency checks to prevent duplicate processing.

.NET cloud developers prepare applications for Azure App Service or container-based hosting. They configure managed identities and secret access, separating environment settings from application code.

For applications that need independent background processing, engineers implement Azure Functions or .NET worker services. They add application telemetry through OpenTelemetry and Application Insights to trace failed requests across service boundaries. CI/CD pipelines in GitHub Actions or Azure DevOps automate testing and application releases, with health checks and rollback procedures matched to the hosting environment.

Maintain existing C# applications while addressing framework constraints or recurring production faults. .NET engineers assess dependencies and runtime compatibility before planning upgrades from .NET Framework to supported .NET releases.

For slow or unstable applications, specialists use profiling and production diagnostics to investigate memory pressure or database contention. They reproduce defects and add regression tests before changing behaviour. Incremental refactoring can separate tightly coupled components without requiring a complete rewrite, while ongoing support covers dependency updates and corrective changes.
