I created tools which install the OpenVZ virtual server environment onto a new server, using Cobbler and Puppet. I have been developing the provisioning scripts in Perl, Bash and Python. I am enhancing the core services such as DNS, Postfix, Shorewall, and Nagios.
I use Java, C++, and JavaScript to develop Web Apps, Rich Client Apps, and Firmware on Linux, *nix, and Windows. My specialty is Air Traffic Management. Recently I have had a blast with jQuery and OpenVZ.
