## Opis stanowiska

Responsibilities:     Designing and building .NET 8 microservices — FastEndpoints, clean architecture (Domain / Application / Infrastructure / API layers).

Strong experience with Azure services, including Key Vault, Managed Identity, Blob Storage, and Application Insights.     Experience with structured error-handling patterns; familiarity with Result/Maybe patterns preferred.    Strong experience with Entity Framework Core or equivalent ORM technologies, including migrations, value objects, and aggregate roots.     Hands-on experience with automated testing using xUnit, FakeItEasy, and Shouldly, including integration testing patterns.     Strong hands-on experience with containerized local development using Docker, Podman, or equivalent technologies.    Good understanding of Dockerfiles and multi-stage builds.
