I build and modernize scalable C#/.NET applications across desktop, web, mobile, and cloud platforms.
GermanyWhat I'm looking for
I've spent 15+ years building and modernizing C#/.NET applications across industrial automation, finance, translation, and healthcare. At Optris GmbH, I led cross-platform Avalonia desktop development for Windows and Linux and optimized gRPC communication for better responsiveness.
I'm currently enhancing a large legacy WinForms application at Genesis Automation Healthcare, working with SQL Server, stored procedures, query optimization, asynchronous workflows, GitHub, and CI/CD. Previously, I delivered ASP.NET Core licensing and product-management platforms, Xamarin mobile apps, REST APIs, and .NET modernization projects.
