I keep public notebooks of working code: .NET services, TypeScript, command-line tooling, Linux scripts, and data work. The repositories are grouped by subject so each one stays a place to practice, not a dump of everything.

Services. .NET Web APIs for reporting filters, JWT authentication, and a call-center API. Desktop and mobile sit beside that in WPF MVVM and .NET MAUI.

Interfaces. An Angular login that talks to a JWT API, plus small web apps: school administration, surveys with charts, and a short-message broadcast app.

Tools. Bash scripts, Azure and local pipelines, Flask with SQLite, a FreeCAD stair designer, and C and C++ exercises.
