About Ken

I support companies in the development and further development of modern software solutions based on .NET and Microsoft Azure.

My focus is on the technical implementation and further development of scalable systems – from cloud-based backend applications to web and mobile solutions.

I regularly work in established system landscapes, taking on both the further development of existing applications and their structural improvement, e.g., through refactoring, modularization, or performance optimization.

Technologically, I primarily operate in the .NET and Azure environment (ASP.NET Core, EF Core, Microservices, REST APIs, Docker), complemented by the development of cross-platform applications with .NET MAUI.

I value clean, maintainable solutions, clear structures, and reliable implementation – from conception to productive use.
