Creating software is my favorite pastime. I still remember how it happened. This passion began from a "calculator". 

When I was a child, I wondered how this simple calculator could help people in artihmetic or in leyman's term, mathematics. In pursuit of the answer to my question, I learned how to make simple programs. It is not as simple as I thought it would be. You need a lot of concentration and presence of mind, logical thinking and perserevance. 

But, whenever you see your software working completely - without any bugs - what a joy!
