About
I've been in the IT industry since 2000. I have a degree in physics but chose to make my career in IT. Currently I spend more time working with system security than writing code but when I have the time I enjoy perl, php and mysql.

Currently working on:

LAMP servers
Postfix
Windows Server 2008
Network Administration
Security Administration
Asterisk
