PROFESSIONAL EXPERIENCE:

AIX/Linux Systems Specialist

Confidential - Cayce, SC

• Worked as a member of the SCANA Transmission Operations Center (TOC) server support team, responsible for operations and maintenance of all IBM AIX 7.1 servers (IBM POWER7 and POWER8 cpu's) and RedHat Enterprise Linux version 6 (on Intel x86/Xeon cpu's). These servers supported 24x7 grid operations with large and sophisticated control room displays for over half of the South Carolina electrical power grid, plus natural gas distribution to multiple states. Control technology included SCADA interfaces for the real-time control of power-generation equipment settings in the field, by operators using AIX-managed consoles and graphical displays.
• Reviewed Security Bulletins and handled security updates/patches to IBM AIX 7.1 servers, which ran some of the most critical enterprise applications at SCANA. Successfully completed AIX security updates for IBM POWER-based servers with minimum downtime, some were executed while live production operations continued. Investigated daily error logs for both software and hardware issues and arranged for on-site maintenance of AIX servers by IBM Support. Required detailed knowledge of IBM POWER-based server platforms, HMCs and related hardware. Supported stand-by AIX servers, maintained at DR site in Irmo, SC for full failover of power grid ops if needed.
• Primary responsibility for Anti-Virus scans and ensured regular downloads of daily AV data files for all AIX and Linux servers using McAfee AV software.
• Supported compliance with extensive Federally-mandated CIP (Critical Infrastructure Protection) regulations for safeguarding US electrical power grids from hacking, penetration attempts and terrorism.

Unix Systems Engineer

Confidential- Charlotte, NC

• As part of the Unix Ops team supported over 1,500 Unix/Linux servers. Work involved problem determination and resolution of Unix/Linux server issues via both Help Desk requests and as part of larger projects such as OS patching/version upgrades, remediation of security vulnerabilities, and application integration/scripting. Supported platforms were Oracle/Sun Solaris 10 and 11, RHEL 5 and 6, and IBM AIX 6.x and 7.1.
• Developed/documented new procedures for applying very large updates to IBM AIX 7.1 servers, which ran some of the most critical enterprise applications, but some of which required very large and problematic updates and enhancements from IBM. Successfully completed full AIX updates for certain production servers where excess downtime could have caused reduced revenues for TWC.

Unix Video Sources Engineer

Confidential- Charlotte, NC

• Supported Cable TV provisioning applications, as used to define channel availability and delivery specifications (like video stream encryption and various On-Demand options) in multiple U.S. market areas.
• Video provisioning work involved CISCO/Scientific Atlanta DNCS (Digital Network Control System) and TWC’s MAS application. DNCS defined program “sources” for specific markets, and these newly defined or revised channel sources were then “published” into all appropriate user channel/content guides and dynamic on-screen listings using TWC’s MAS software.

AIX Systems Engineering Specialist

Confidential- Savannah, GA

• Provided technical support for IBM AIX and Linux x86 servers, some running Oracle databases and others hosting high-end 3D CAD applications for aerospace engineering work, such as ‘Dassault CATIA’.

• Used IBM WebSphere Application Server for management of hosted webpages and for control of locally maintained web applications.
• Worked for OPENET’s Solution Performance Team in support of performance testing to validate applications as meeting targeted transaction rates and other service level thresholds, as developed with, and expected by, given clients. Used Atlassian JIRA to document and track progress of performance issues.
• Configured PUPPET profiles on master server for automatic installations and configuration updates to multiple Red Hat Enterprise Linux servers. Completed formal AGILE Training.
