Experience

NASA Unified Information Technology Services Contract:

CSC/IBM/SAIC March 2002 - Present

Since March of 2002 I have been working on the NASA UNITeS Contract. This contract provides a variety of Information Technology services to NASA. These services range from WAN connectivity among NASA sites, to a NASA-wide e-mail system, to an integrated financial management system using SAP. Because of the diverse and changing nature of the contract, I have had the privilege of working for several excellent companies during this time. Also during my time on the UNITeS contract, I took the opportunity to broaden and deepen my capabilities by participating in several different job roles.

Systems Engineer,

IP Address Management Project

The IP Address Management Project is an on-going effort to consolidate all of NASA’s Internet Protocol address space into a single management infrastructure. To achieve this goal, we have successfully deployed the IPControl product by BT Diamond IP. This software provides a centralized database and management tool for DNS, DHCP, ASN, and user-defined data.

I was recruited to the team in early 2008. My responsibilities include providing migration planning, engineering, and support to thirteen different NASA organizations. I am responsible for interfacing with the support staff at each of these organizations to collect their network data. After data collection, I work with the IPAM architecture team to get the site’s data converted for import into the IPControl system. Then, I develop plans for replacing the site’s existing DNS and DHCP servers with new ones managed by IPControl. These plans are very detail-oriented, and must include integration with Microsoft ActiveDirectory’s service resource records and potential changes to a site’s network infrastructure. Finally, during migration, I am responsible for being on-site and coordinating all switchover activities.

Some of my other responsibilities include writing automated testing utilities in Perl to validate DNS functionality and firewall rules. I developed and maintain a Perl program that authenticates users of the IPControl product using NASA’s agency-wide LDAP system. I develop test cases, and execute them in the IPAM lab environment. I coordinate customer testing with the IPAM Operations group. I make presentations to our customers, and I provide regular schedule updates to project management. I am also responsible for ensuring that the deployment to each of my sites conforms to the appropriate NASA Security Plan.

This project is scheduled to conclude in April 2009.

SAP BASIS Administrator,

Integrated Enterprise Management Program

The NASA Integrated Enterprise Management Program (IEMP) is an effort to deploy an Enterprise Resource Planning package for the NASA community. Computer Sciences Corporation held this contract until April 2004, IBM held it until December 2007, and SAIC holds it now.

In January of 2007, I took advantage of an opportunity to broaden my skills in service to NASA after five years as a senior member of the UNIX team by moving to the SAP Basis group.

Because I understood both the Solaris and SAP implications, I was responsible for providing domain layout and system configuration for the migration of SAP R/3 and Business Warehouse production application servers to the new Sun M5000 systems. This included the conversion of /etc/system parameters in Solaris 9 to the project-based parameter system in Solaris 10. I performed proof-of-concept testing and system administrator training for the migration.

I installed and configured new SAP NetWeaver instances to support fiscal year end testing and production.

I performed instance refreshes from production systems to test and development systems.

I wrote Perl and Bourne shell scripts to perform SAP application monitoring and control. These scripts included monitoring filesystems such as /usr/sap/trans and automated processing of system transports.

I recorded and modified SAPGUI scripts to automate system administration tasks.

I worked with the Basis Architecture team to create a flexible farm of SAP dialog servers for Systems Integration Testing. In this server farm multiple dialog instances were installed on each server, and work- load was controlled with the Solaris Resource Manager and Fair Share Scheduler. With this server farm, we were able to quickly respond to the dynamic business needs of the testing team by providing extra system resources precisely where and when they were needed. The Systems Integration Testing was a complete success, and we were able to meet our production goals.

Senior UNIX Systems Administrator,

Integrated Enterprise Management Program

I provided expertise to install and configure new Sun Fire 15000 and Sun Fire E25k servers, including domain layout, System Controller configuration, and Dynamic Reconfiguration of running domains.

I provided expertise in UNIX system administration to support the SAP environment running Sun Enterprise 10000, Sun Fire 15000, and Sun Fire E25k Servers in a multi-domain environment.
