    "The Last couple of years I have worked on everything from big server farms where scalability was important, to high availability clusters where uptime is critical. I have worked in big teams, and on my own, supported everything from, application servers, (example: zope2,zope3,tomcat) databases servers, (example: mysql, postgresql, oracle etc) email servers. (example: postfix and exim) I am able to script and create safe automated tools for developers to use when I am not around. Creating tools for developers, to make their jobs easier is a big part of a team oriented system administrator. My objective is basically to pay my rent and do a good job, I want to be happy with what I create and the time I spend doing it, and of course the most important thing is that I want my clients to be happy with my work. I take time to talk to my clients, and not just stress through projects and forget about life. I want to make my work place into somewhere I enjoy being, rather then something to be dreaded. Call me crazy but I think that if I enjoy doing my work, I will do a better job for you"  less
