.NET Developer | C#, UWP, ASP.NET Core

I build reliable desktop and web software with C#, .NET, ASP.NET Core, and SQL.

My work spans Windows applications, APIs, and product features that need to stay maintainable over time.

I'm looking for .NET roles where I can own features, collaborate closely, and keep growing on the backend.
