Objectives
I am interested in technical opportunities which would fall into one of the following categories:
Unix System Administration
I have been working with Unix systems of many " avors" since rst exposure to Digital Ultrix in
1986, including, professionally, SCO, Digital OSF/1, Linux, HP/UX, AIX, and Solaris.
Having had a diverse set of academic involvements, I would also be comfortable with the idea of
doing instruction/training with Unix or Linux.
Unix Systems Integration
Long term exposure to various " avours" of Unix, as well as to many of the scripting tools, and quite a
number of applications would be helpful for connecting software particularly to ERP systems like
SAP R/3
Professionally, I have scripted processes using Perl, Python, Korn shell, and the Bourne shell. I have
also had exposure to many other scripting languages including Tcl and PHP.
SAP Basis Administration
Preferable platforms would involve some avor of Unix as the OS, and Oracle as the underlying
DBMS.
Areas of special expertise are the CTS (Corrections and Transport System) change management
system and the ABAP/4 programming language.
Education
