Employment:
• 2007 to April 2009 – MMC (Marsh and McClennan) – Senior Engineer ESM Engineering
o Enterprise Network Management – Responsible for new product R & D working with new network hardware (routers, switches, content switches) to both develop new management concepts and to integrate existing element managers into the Global Management environment. This includes interfacing with vendors, running pilot projects and developing new code when needed.
o Project Manager – Responsible for the re-design and implementation of a new global Spectrum 9 Based ESM system. This includes both the standard Network integrations as well as integration server management (agent and agentless) into Spectrum – integrating CA Unicenter infrastructure.
o Responsible for the integration of various vendor tools into the Spectrum environment, these include CA Service Desk, CA Unicenter, HP NAS and various in house web reporting interfaces.
o Responsible for evaluating new releases of current network management software to insure compatibility with the current management environment.
o Responsible for certification of new network and systems hardware into the Firms ESM infrastructure. This requires vendor and engineering team coordination resulting in production turnover of complete monitoring solutions.
o Tier 3 support for the entire MMC Network Management tools suite
Previous Employment:
• 1998 to 2007 – Bear Stearns Inc.- Vice President Enterprise Management Tools Research and Development
Projects
• Project Manager – Responsible for the implementation of a Network Device Configuration Management and Compliance system – Opsware NAS. Project scope includes hardware purchase decisions, network integration, application install, application configuration and integration with existing IP discovery tools. Ongoing development and design work to integrate Opsware into the Firms workflow and project management systems (Remedy) and the Firms IT Security systems (Novell Sentinel)
• Project Manager – Responsible for the design, development, purchasing and integration of a ‘next generation’ Network and Systems management infrastructure at the Firm. This new environment will consist of Blade server based cluster computing using both existing management tools and new tools evaluated in the past year. The final purchase decision will use HP Openview, OpenSystem NerveCenter, Microsoft MOM, IBM Netcool, IBM Impact and various other tools. Project was completed in early 2007 and delived on time and within budget.
• Worked with Cisco in developing and implementing a monitoring strategy for a high availability, multicast based trading infrastructure. The low latency monitoring was performed with Corvil as well as SevOne. Open source alternatives were also developed for this project.
• Enterprise Network Management – Responsible for new product R & D working with new network hardware (routers, switches, content switches) to both develop new management concepts and to integrate existing element managers into the Global Management environment. This includes interfacing with vendors, running pilot projects and developing new code when needed.
• Designed and implemented an IBM Blade Server based lab environment for testing new network management products against a variety of new LAN and WAN products. This included design, procurement and implementation of various network management products
• Responsible for the design and development of network device behavior models within products such as Open Systems Nerve Center. These models are used to manage both existing devices and new devices being implemented.
• Responsible for evaluating new releases of current network management software to insure compatibility with the current management environment.
• Responsible for day to day support of the current Global Network Management infrastructure. This includes all LAN and WAN monitoring tools both developed in-house and vendor supplied as well.
• Designed and developed many SNMP based applications for performing various network device related tasks in the Firms production and security environment.
• Designed and developed applications such as automated paging systems, process load balancers, email parsing gateways, and environment dependent process launchers.
• Evaluated competing SNMP technologies for event correlation and downstream error suppression. Used this evaluation in picking a vendor to supply this technology to the Firm.
• Designed, developed and maintained SNMP Behavior models using the Nerve Center management tool. These models were used to poll all of the Firms network devices to collect MIB data, evaluate the collected data and send alerts into the network management platform (Netcool & HPOV). Part of the design and evaluation process included the evaluation of vendor specific MIBs as well as working closely with the various vendors to bring changes to the MIBs to enhance the Firms operational capabilities.
• Provide level 2 support for all of the Firms network management systems as well as the UNIX and NT platforms these systems ran on.
• 1991 to 1998 - Salomon Inc.- Senior Network Engineer
o Network Tools Design and Development
• Worked on a team responsible for the design and implementation of a global network management platform based on HP Openview. My responsibility included the evaluation of HPOV, Netview and Cabletron Spectrum as well as evaluation of event correlation tools such as SMARTS, NerveCenter and Omnibus Netcool. I am currently integrating HPOV in the NY/NJ Metro network.
• Designed and implemented a SNMP Based Global Network data collection and reporting system based on the TRENDsnmp product from Desktalk Systems. This tool collects data from network devices and builds network trends over time. The statistical reporting is made available via a web interface which I designed and built.
• Was responsible for day to day support of the current Global Network Management infrastructure. This includes all LAN and WAN monitoring tools both developed in-house and vendor supplied as well as tools for monitoring and management of the ATM and switched Ethernet environment (Foreview).
• Implemented various network management and monitoring platforms including Sun Net Manager, Cisco Works, TRENDsnmp and HP NetMetrix. In addition, developed tools which interact with these base platforms for processing of SNMP traps.

Distributed Network Software
• Designed and develop an UNIX based LU6.2 gateway allowing multiple secure LU6.2 access into the firms mainframe systems.
• Designed and implement a socket based application for the distribution of vendor supplied market data (news).
• Designed and implement a UDP broadcast bridge where UDP data is tunneled across router serial links as point to point transmission.
• Acted as project lead in bringing TCP/IP communication the Firms mainframe systems. In addition, I designed and developed a set of simple API's where applications which once used LU6.2 communications to access mainframe resources could access mainframe systems via TCP/IP (socket).
