Love to develop applications with Groovy, Grails (and Java)
My name is Hubert Klein Ikkink, but I am also known as mrhaki. I am born in 1973 and live in Tilburg, The Netherlands, with my beautiful wife and three gorgeous children. 
I studied Information Systems and Management at the Tilburg University. After finishing my study I started to work at a company specialized in knowledge based software. There I started writing my first Java software (yes, an applet!) in 1996. During the years my focus switched from applets, to servlets, to Java Enterprise Edition, to Spring based software. 
In 2008 I wanted to have fun again when writing software. The larger projects I was working on were more about writing configuration XML files, tuning performance and less about real development in my eyes. So I started to look around and noticed Groovy as a very good language to learn about. I could still use existing Java code and libraries and can use my Groovy classes in Java. The learning curve isn't steep and to support my learning phase I wrote down interesting Groovy facts in my blog with the title Groovy Goodness. I post small articles with a lot of code samples to understand how to use Groovy. And since November 2011 I am also a DZone Most Valuable Blogger (MVB), where DZone also posts my blog items on their site.
