I am a programmer and developer of more than 30 years' experience.

Began as an electronics designer, but soon started assembly programming, and then C++, Win32 API (still my favourites), Java, Android apps, C# Desktop applications on security, C# ASP.NET classic, C# ASP.NET MVC, and now I am busy with ASP.NET Core.

I have a classroom teaching experience of about 20 years.
