Senior UNIX Administrator
Engineered and implemented new UNIX systems on a project basis. Determined the client’s needs and put together the solution while meeting their requirements. Upon arrival I would install the system in the datacenter and jumpstart/kickstart it loading the software needed. Once the operating system was installed I would configure the system and attach any SAN or NAS drives to it. This often entailed configuration of veritas volume manager and file system, Oracle databases and Apache or Apache tomcat web servers.
Server installation included a global sendmail gateway solution utilizing 2 Sun R250 in the US and 2 in the UK that relayed to 5 Compaq Zeon’s running Red Hat AS 2.1. Apache Tomcat and Jakarta portal system. Apache Tomcat and Jakarta development platform. Several Oracle development systems and A Ticket management system using Remedy.

CSC, Raleigh, N.C. 1999 – 2003
Consultant
Clients: Nortel. RTP, General Dynamics USMC, General Dynamic ATS
System Architect / Engineer
Assisted in architecting and implementing a global backup solution. Working in a team environment we investigated, redesigned and implemented a stable and more organized solution. This included analyzing all master backup servers and redefining the backup classes to a standard that was easy to understand resulting in better fault tolerance and instant notification to be sent on failure which could be addressed immediately.
Network Security Administrator
Designed and implemented a secure Internet environment at new site location. The project was accomplished using a Check point NG firewall with secure remote accessibility. With my knowledge of Windows NT 2000 and Red Hat Linux I utilized a Red Hat 8 server running a squid proxy and using SAMBA which gave me the ability to allow the Windows NT user database to do the authentication without prompting the users to access the web. Implemented two intrusion detection systems, one was an open source solution called SNORT running on Red Hat Linux, the other was ISS real secure running on Solaris 8. This provided redundancy and allowed for false positives to be better detected.
Utilized a Red Hat Linux solution using Squid and SAMBA tied into an existing Windows NT 2000 network saving the company from buying a proxy server while also providing a single sign on solution.
Because of my knowledge with Red Hat Linux I was able to save the company thousands of dollars utilizing open source solutions and providing better security.
