Description

Senior Software Engineer with a focus on backend and fullstack development in the .NET and C# environment. I support companies in the development, modernization, and stabilization of business-critical software solutions, from scalable REST APIs and complex backend systems to fullstack applications with Angular.

My focus is on C#/.NET, ASP.NET, API Design, SQL databases, and the integration of distributed systems. Additionally, I bring experience in Java and Spring, Docker, Kubernetes, and CI/CD environments. I work in a structured, solution-oriented manner with a high standard of quality, both in Greenfield projects and in the further development of existing enterprise systems.

I typically take on projects in the areas of backend development, system integration, API architecture, and technical further development of complex platforms.
