Built and maintained servers and workstations in sixteen offices throughout the Missouri and Illinois areas. Proficient at solving problems over the phone or via MSN Messenger.

Owner

The idea behind Kurodenkou LLC was to provide an official channel to do consulting work where applicable.  Kurodenkou LLC is a Tucows (OpenSRS) partner, and provides domain name registration.  The ability to walk into an opportunity as a legitimate business and not just a contractor opened a lot of doors and allowed me to expand my knowledge via product trials with F5, SSL Certificates through StartCom, Cisco, Redhat, and various other companies.  

Hosting Incident Response Specialist (System Adminsitrator)

Worked on UNIX and Windows systems for dedicated clients.  Duties involved active monitoring through IBM Tivoli Netcool and troubleshooting/triage issues.  Primary responsiblity was to keep the environment alive while improving it.  It was necessary for the System Administrator to make every effort to resolve an issue before engaging an Engineer.   Specific troubleshooting included unresponsive servers, slow server, or servers with some sort of defect (bad hard disk in the blade).  Mostly responsible for tasks such as mitigating high CPU usage or disk space issues.  Backup failures are a big part of the job as well.  Application support ranges from IIS to Apache to Oracle.  Experience with 200+ RHEL 5.x boxes, as well as many Windows 2008 R2 Boxes.  Was responsible for major documentation including repeatable procedures around the Cisco ACE.
