  • Architected, built, and currently maintain a cluster of 6 MS Exchange 2000 servers with a Sendmail frontend. The Exchange servers are comprised of 5 mailbox servers and 1 SMTP gateway. The sendmail server is a frontend server that receives mail from the internet, and checks DNS blacklists before forwarding the mail to the SMTP gateway which then does spam checking, virus checking, and forwards the mail on to the individual mailbox server.

The MySQL servers are a master and slave which are using replication as well. These are 5 database servers in a datacenter of over 10 database servers, all of which I manage.

 

  • Installed, configured, and currently maintain a Nagios network monitoring system which monitors everything from host availability, service availability, and our datacenter HVAC system and battery backups. Respond within 30 minutes to any outage reported by the software on a 24x7 basis.

HOBBIES

 

I program as a hobby both inside and outside of the workplace. I have written things such as C programs that interface to a Microsoft SQL server using blowfish encryption to an extremely complex IRC robot in Perl. I also wrote a Radius Authentication and Provisioning system in C and Perl to update/authenticate off of a backend MySQL Database using libmysqlclient and DBD::mysql Perl modules.

I am an extremely quick learner and enjoy discovering new things and acquiring new skills. Anything that is thrown at me is something I will enjoy doing, especially if it is something I have never done.
