• Worked on the Serviceguard product, a high-availability clustering product developed in the HP-UX lab.

As security specialist, I did security audits of existing features, planned new security functionality, wrote documentation, participated in security patch releases and gave several instructional classes to other developers about security and Serviceguard.

• Combination of systems administrator, data scientist, web designer and programmer.
• My primary responsibility was to manage web traffic analysis for MGM.com properties. This meant maintaining redundant WebTrends machines (Solaris and Linux), managing the work flow of retrieving logs via FTP and loading them into WebTrends. Recovering data when these fragile systems failed. I was also the goto web traffic analysis expert so I'd setup reports for various questions the marketing people at MGM had.
• Eventually I wrote a fairly extensive python application for doing log management. It automated the downloading, recovering, pre-sorting and data cleanup that was necessary to make my job less painful.
