"Everyone knows that debugging is twice as hard as writing a program in the first place. So if you're as clever as you can be when you write it, how will you ever debug it?" ~ Brian Kernighan
About Me
I'm software developer with several years of practical experience. I have the greatest knowledge of PHP language and web applications are my domain. However, language is only tool for me. Depending on needs, I can use Python or Java. My code is focused on the readability, simplicity and reliability. In addition, it must be: easy to test, easy to extend, easy to reuse and fast as lightning.
