Welcome to Existon!

I am an engineer in electronics and biomedical systems, a physical scientist and also  an artist, somewhat funny and somewhat hilarious, reverse psychologist, master empathologist, project manager and consultant. I have a great interest in computers, technology, electronics, science and everything living. In the projects section you can find information on a few projects I have been involved with. Have a look at my CV here.

To Code is to create

My favourite languages are C, C#, Java, VB.Net, PHP, JavaScript and Pascal. I like Visual Studio and Android Studio which are my favorite programming platforms.

Crude Map of the Universe

The Universe can be defined as everything that exists, everything that has existed, and everything that will exist. According to our current understanding, the Universe consists of spacetime, forms of energy , and the physical laws that relate them. The Universe encompasses all of life and all of history.
