I am a C# software developer, having written a few libraries/snaps/applications from the projects I'm experimenting on.

My name is Ruhan, curious on how things work (software wise) and a person with deep knowledge on
industrial control protocols, embedded computer hardware and a insatiable itch for diagnosing and fixing problems.

Currently residing in Pretoria, Gauteng, South Africa.
