Used UNIX and Solaris system integration and troubleshooting skills to remotely support or travel to operational customer sites for support of Solaris system upgrades, and post upgrade trouble shooting. This included distributed access management, and Solaris patch security mitigation. Ensured the Oracle database integration. Used knowledge of Windows & UNIX based operating systems, to upgrade, maintain, and troubleshoot large government systems. After upgrade, used knowledge of Netbackup and Liveupgrade to backup, restore, and patch Solaris systems. Worked with a small team of experts but mostly worked independently to resolve issues in high pressure situations. Used knowledge of UNIX shell scripting (ksh, bsh, & pl) to solve issues and develop enterprise solutions. Used Clear Quest to relay issues found at different customer sites back to the factory. Worked with COTS and the COTS lifecycle to design and document Solaris operating system architecture/designs for large distributed systems. Participated in system performance tuning. Used LDAP administration to verify domain authentication. Debugged Apache, Tomcat and Oracle issues. Used Windows experience to architect, build, configure and support web products built on the Microsoft stack. Including Windows Server 2003, and Windows Server 2008. Gained knowledge of web services (SOA), MS SQL Server, MSMQ, and multi-tier application systems. Experience in Software Configuration Management, source control, build engineering, and system administration in virtual environments. Supported vendor applications in Windows & Oracle distributed environment. Verified SLAs could be supported. Combined customer contractual needs and requirements into system test solutions that acknowledged technical, schedule and cost constraints. Established functional and technical specifications and standards, solved hardware/software interface problems, defined input/output parameters, and ensured integration of the system and subsystem.

I used Solaris system administration skills to administer test environment. Created scripts to automate installation of software on Solaris platform. Administered Oracle Database. Used Rational Clear Quest to track default request and change request. I responded to user’s trouble tickets, by debugging and fixing issues that they were experiencing. Ran Clear Quest to update status on different problems and changes/updates being worked. Used Clear Case to promote development changes for different engineering releases. Re-imaged Windows workstations added them to the network and joined them to the domain. I used Active Directory to administer user accounts, workstations, and servers. Solved hardware/software interface problems, defined input/output parameters, and ensured integration of the entire Solaris system and subsystems. Planned, implemented, tested, documented, and maintained solutions for the integration and testing of in-house developed and COTS/GOTS components, elements, systems and subsystems. Created test procedures to test individual COTS/GOTS products as well as the interface between the products and custom software developed in house. Coordinated, scheduled and implemented Formal Acceptance Testing with the customer. Developed test plans for the entire testing team. Scheduled and lead testing activities for major releases. I was responsible for VMware visualization implementation. Reviewed, evaluated and derived requirements for testability. Directed preparation and execution of comprehensive test plans, procedures and schedules for complete systems and subsystems. Coordinated subsystem and system testing activities with programs and other organizations. Performed analysis of test results and prepared comprehensive system level evaluation reports which verified and validated system performance. Wrote discrepancy reports and performed integration regression testing to verify/validate incorporated fixes to software, subsystems and systems.
