Senior member of the lab support team responsible for the building, patching and support of the lab servers. These servers run custom software and third party software. The servers support the development, upgrade and testing of software used to support the Hughes’ satellite operations.  Built, cloned, maintained and patched Linux (Redhat, CentOS, SUSE) and Windows servers in a VMware environment. Designed and implemented a patching system to support the Linux servers. The servers sit behind firewalls with limited access to the external world. The system uses main repository servers with external access to sync with the Redhat network to receive the required package updates. The internal servers then access the main repository servers for automated updates. Work in the lab datacenter to rack, install software, upgrade and maintain the server hardware. Tasked with routinely fixing user issues in a timely manner. Support DBAs and Developers during the multiple deployments of new products to the Data Centers.  In the process of deploying a CACTI / ZABBIX combined monitoring system for servers in the lab datacenter.

Senior Infrastructure Engineer tasked with building, upgrading and maintaining the Solaris hardware and software platforms located in the WUBS data centers. - Built, maintained and patched Solaris LDOMs and Zones used to support WUBS products and databases.- Worked with the DBAs to build out servers for Oracle Rac cluster database deployment.- Responsible for the operation and maintenance of the Nagios tool that is used to monitor the operational state of the servers in the WUBS data centers.- Monitored the growth of the processes running on the servers and implement the changes needed to increase the resources and sizes of the servers hosting the WUBS processes/products. - Supported Compliance and Security checking and the resolution of any issues found. - Provided 2nd and 3rd tier data center support for both Solaris servers and WebLogic middle issues.- Used HPSM (HP Service Manager) ticketing system to support Change control and issue management. - Supported DBAs and Developers during the multiple deployments of new products to the data centers.

Senior Software/Infrastructure Engineer tasked with upgrading and maintaining the hardware/software platforms currently in use in FINRA’s data centers. This includes maintaining some of the required vendor licenses like BeyondTrust (PBIS) and Red Hat (RHEL). I assisted in the movement of the of the FINRA operations out of the Plano and Charlotte data centers into the newly upgraded Rockville and NY4 data centers. The work included modifying the standard configuration build image requirements to meet the changing needs of the FINRA Platforms being used along with helping to build the new servers and install some of the required software. I assist the System Administrators with task required to support the data centers. I worked to stabilize the process of authenticating users to our Linux/Unix servers using Windows Active Directory as the authenticator. The PBIS(Likewise) software by BeyondTrust was used as the AD bridge. I am now working on introducing Red Hat’s SSSD Active Directory authentication software into FINRA’s environment. I am also working on the upcoming task of retiring the Sun (Oracle) OS/Hardware platform and replace it with Dell Hardware running Red Hat Linux OS. I also worked with the processing of CR tickets through the Change Control System. This task required the gathering of information from the various groups, recommending what changes should be requested as needed and monitoring the movement of the tickets through the system. I was tasked with designing/building/maintaining the Proctor hardware/software environment. This included writing/implementing design specifications for a multi-environment lab using Solaris Containers. The Proctor program operates on both Solaris and Windows XP platforms. The software was/is written in C/C++, Java, Visual Basic, VBScripts, Unix Shell Scripts and database SQL routines.

Tasked with developing/testing new software (written in Object Oriented C on HPUX version of UNIX) and enhancing released software with emphasis in client/server n-tier environment. Manage internal coding, testing, and maintenance of software for internal use and sale to external customers. • Unit and System tested modifications made to the High Volume UNIX mail reader (e-mail) system before delivery to the QA group. Also assisted production in identifying specific problems occurring in the live system.• Enhanced e-mail UNIX server, written in OO C, for 20 million customers in performance-driven, 365/24/7 environment by adding HTML handling features along with other client required upgrades. Also added features to check the incoming data for possible hacker attacks.• Developed new server to add information security by modifying specific employee operating privileges. The new server was written in C and TCL and operated in a HPUX UNIX environment. The server it replaced was written in PL1 and operated on a Stratus machine. • Modified code and added e-mail cell information to overhaul return receipt processing, ultimately adding value to e-mail system for customers by correcting information on return receipts. • Used CVS Configuration Management tool for source code control.• Software was written in object oriented C and TCL on HP workstations and servers running HPUX. Data was stored in Sybase and on Tandems. Testing was done using clients running on Win98, WinNT and Mac machines. Testing was also done using TCL commands on the servers along with GDB. Software maintenance and support was done as needed.

Worked on software maintenance, upgrades to released code, coding, functional testing and unit testing of C/C++/Fortran code and databases, and modifications to software and UNIX scripts. Provided customer support for installation and maintenance issues. Collaborated with sales and marketing to match software performance with customers’ needs. Led crisis management, network troubleshooting, and customer satisfaction tasks. • Actively involved in testing and coding of the PNMS project that ported/migrated Prime-based software written in FORTRAN to software written in FORTRAN and C on a Data General DGUX (UNIX) platform, creating faster, more robust programs and greater capacity for platform support.• Maintained Fault Management program (TPRF3), written in FORTRAN, which monitors operation of network equipment and provides real-time collection and processing of alarms, statistics and accounting data. • Coded, debugged, tested and maintained Proxy Agent program as a new NMS client to monitor network software/hardware. Program was written in C and C++ on a Data General running DGUX (UNIX). UIMX and X/Motif was used to create the GUI while SNMP was used to allow clients to access the program over the Internet.• Piloted Interbase relational database redesign to increase performance of Proxy Agent program, achieving improvement from 15 transactions to more than 250 per second on 80 MIP UNIX machine. The new design was also more effective at securing the database information. SQL calls were embedded in the C/C++ modules for database access. Program was later modified to also use CMIP calls to the NHM program, which used API calls to extract information from an Oracle database.• Tested Proxy Agent server performance using HP Openview, which was operating on multiple Sun UNIX Workstations running Solaris, to produce SNMP MIB information requests.
