I'm passionate about technology, and particularly helping people make the most of it. I've spent the last 30 years helping others make the most of technology. My career started in IBM, and I've since moved into smaller business environments, to find those that have the biggest steps to take. My skills range from user based technology, through business systems (applications) to infrastructure. I also have a long background in IT security. I focus on what I consider to be "productivity technology", i.e. adding genuine value to peoples lives. I'm not a big gamer, or hold much interest in the disposable consumer technologies. During the day, you'll find me consulting with businesses or heading up an IT department. At the weekend, you'll find me sat at my Linux desktop PC, writing PHP or Python code, or trying to help others on Twitter, this blog, or my YouTube channel: Artexic.
