Nature of work · API and service implementation

Build .NET Core/ASP.NET Core microservices and REST APIs, wire Kafka/CDC event flows, and tune PostgreSQL/EF Core data access while helping with backend architecture and production support.

"Build and maintain microservices using .NET Core, C#, and ASP.NET Core"

Tech stack maturity

Mainstream Modern

The stack centers on ASP.NET Core, .NET, PostgreSQL, Kafka, Entity Framework, and OpenAPI, which are widely adopted contemporary backend technologies rather than cutting-edge cloud-native or legacy-only tooling.
