Apart from being a Java developer, I enjoy most of my time with my children and being outdoors. In the winter, I love skiing and during the warmer months, I enjoy playing beach volleyball.
When forced indoors, I follow a number of sci-fi and fantasy genre movies, I am slowly becoming a chef, and I spend a large amount of my free time exploring the latest technology advancements in the Java and ops world.
