Senior backend developer, 15+ years designing and building production systems in C#/.NET and Golang — REST APIs, SQL Server, EF Core, system architecture. 10+ years as a senior C# developer building enterprise billing and back-office systems end to end — architecture, implementation, and long-term maintenance. I also have hands-on experience with PDF and document-processing libraries, used in production by other companies' software. I also work across cross-platform and Windows desktop development (Blazor, WinUI3), and have applied experience with AI and computer vision.
