Build robust and scalable solutions: You will develop Batch, APIs (OpenAPI) and services (.NET Worker Services) in .NET 6 or higher, as well as microservices in .NET 10 / C# 13, applying SOLID, Clean Code, Onion/Clean Architecture and DDD principles.

Modernize existing systems: You will migrate solutions built in .NET 4.8 to current platforms, so that the business gains maintainability and the ability to evolve.

Designing data with performance in mind: You will design and optimize schemas in SQL Server (indexes, query tuning, execution plans) and program in T-SQL (functions, triggers), using Entity Framework Core (mapping, migrations, LINQ) and Dapper where high performance is required.

Bringing solutions to production from start to finish: You will build multi-stage Docker images and deploy them on OpenShift/Kubernetes (Deployments, ConfigMaps, Secrets), with CI/CD pipelines in GitHub Actions, and publish ASP.NET Core applications on IIS / Windows Server (Application Pools, bindings, HTTPS, SSL/TLS certificates).

Ensure service observability: You will monitor application behavior with IIS Logs, Event Viewer, Application Insights, and OpenTelemetry traces, including prompt and alert logging, to detect problems before they impact.

Resolve incidents and requests to the root cause: You will retrieve, analyze, and resolve tickets in test and production environments, diagnosing logs, traces, and events to identify the root cause.

Sharing knowledge and closing the loop with quality: You will document each solution, update the team's knowledge base, and coordinate with the functional and QA areas to validate the resolution before closing the ticket.

Ensure quality and security in every delivery: You will write unit and integration tests with xUnit / NUnit + Moq (coverage ≥ 80%), review code on pull requests and implement authentication and authorization with OAuth 2.0 / JWT.
