Interests

Apart from being a technology enthusiast, I enjoy a good of my time being outdoors. In the summer, I love exploring trails and I am a novice trekker. During the colder months, I prefer spend my time indoors; socializing with friends.

When at home, I follow sci-fi and fantasy genre movies and television shows, I play Civillization V, and I spend a large amount of my free time exploring the latest technology advancements in the software development world. I also closely follow the developments in software bell-weather firms so that I have a good sense in which direction the industry is moving in.
