Contact information

My current role is Manager of the Enterprise Systems group of ITS, University of North Carolina at Chapel Hill. This group consolidates all the Linux, Solaris and Red Hat system administration across ITS. The group currently manages in excess of 650 systems on IBM's Power platform, Oracle's Sun Sparc platforms and X86 platforms. These servers support Chapel Hill's PeopleSoft implementation, Oracle and MySQL databases, Blackboard and Sakai learning management systems, central Identity Management systems and various flavors of Web stacks. The group is also responsible for delivering large portions of the www.unc.edu web presence and provides a centralized logging service based on syslog and Splunk currently managing approximately 80GB of log data per day.

Prior to accepting a full-time position with UNC Chapel Hill I contracted through ettain group to the university. UNC brought me on initially to provide Solaris 9 and Solaris 10 technical advice, mentoring and architecting. I then moved to fill the role of Manager of the Information Management Group, which provided operating system support for Solaris, Linux and AIX. Other projects included creating a Unified Messaging Architecture as part of the planning for a Unified Communications strategy, and creating an interim Configuration Management process.

Previously I was a Senior Instructor for Exceed Education Services, where I delivered high-end Solaris courses, Sun Java Enterprise System courses, Sun Identity Manager courses and others. I was responsible for the network infrastructure and all the Solaris machines.

Prior to Exceed, I was a Systems Architect - LDAP for Metlife, supporting Metlife's LDAP directory services. My responsibilities included directory design, implementation and support for the nine LDAP directories running in 4-way multi-master replicated architecture on Sun Microsystems Directory Server 5.2.

I am ITIL Foundation certified, with experience in providing support in data centres, large corporate offices, and small business covering a variety of platforms including Windows, Macintosh and Unix. I have strong desktop, Unix, networking and infrastructure skills. Have been in the IT industry for more than 20 years working primarily in multi-vendor environments, and have broad experience in the inter-operability of heterogeneous environments. I have also worked in secure computing environments, and have a high awareness of security issues and requirements including HIPPA, FERPA, and Sarbanes-Oxely.

I have excellent written and verbal skills and experience in technical management, technical support, and technical pre-sales. I am seeking a senior technical managerial role or senior technical role in the Raleigh, North Carolina region.

Provided second level support for Netdynamics and RSA Keon security products.

I was an integral part of the Technical Architecture Group as a Solutions Architect from late December 1997. This was primarily a pre-sales role, and during my time there I worked on bids including:

• Facility management of NT database and applications servers
• Integration and management of OpenVMS systems
• An IVR/CTI application
• 'Right-sizing' a legacy MVS-based application onto a Unix system
• Re-engineering of the EDS (NZ) Output Management service line
• EDI systems
• Image and data capture application

I provided significant input into other bids providing network design, network security design and Unix sizing and deployment.

Following a restructure to allow EDS to focus on a major consolidation project the Technical Planning and Contingency Group ceased to exist, and I was attached to the UNIX & DBA Distributed Support team. While there I continued working on the Pre and Post Sales due-diligence projects related to EDS taking over the functions, premises and staff of Tritec. Subsequent to the start of that contract I worked on the project to integrate the ex-Tritec staff into the EDS (NZ) corporate infrastructure. I had significant input into the infrastructure design, and was primarily responsible for the building and configuring the Samba product to allow the existing Solaris server to participate seamlessly in an NT domain environment with Samba using the EDS NT domain authentication environment.

This group was tasked with:

• Integration of corporate technology strategies
• Development of local technology requirements
• Evaluation of emerging technologies
• Technology obsolescence planning
• Technology selection strategy
• Business recovery planning

While in this group I was engaged in the setting of standards for our desktop environment and starting work on the process to move EDS (NZ) to the EDS corporate Consistent Office Environment.

My areas of responsibility within the group were the desktop, server and Unix platforms.

I was heavily involved with the EDS/DSW Tritec business where I worked on the due-diligence process with particular responsibility for the Unix systems and support. I was subsequently involved in the project for training to enable skills transfer, the technical infrastructure integration and the EDS/DSW inter-operation.

This group carried out the systems functions creating and supporting the technologies to design and implement the infrastructure to support client server applications. During my time in this group I was primarily involved in the following tasks:

• Design and implementation of the EDS (NZ) Ltd corporate intranet
• Facilitation of technical changes, and technical coordination and design of networking to support people moves resulting from merger of the two companies
• Pre-sales input to DSW Data-warehousing proposal
• Reviewed and signed off IRD Internet Security Policy
• Team coordination / backup while manager absent (2 specific occasions - 4 weeks and 2 months)
• Service delivery management functions for CIO including technical quality reviews/assurance of designs for corporate infrastructure projects. Technical consulting for mail migration project and corporate LAN stabilization project

Accountabilities included:

• Platform-level support and advice particularly in the Unix and distributed systems arena
• Provide technical product testing and evaluation
• Conduct research in emerging open technologies. Areas of particular responsibility were open networking, e.g. TCP/IP and systems security
• Unix systems installation, administration and support

Projects during this period included:

• Integration of a TCP/IP network into a proprietary mainframe environment
• Implementation of a mixed Uniscope, TCP/IP, SNA, X.25, X.32, and EFT/POS network including design of the mainframe EFT/POS implementation
• Specification and testing of a locally built X.25 terminal capable of UTS emulation
• Network design, software implementation and maintenance the systems at the Wanganui Computer Centre, including traditional Uniscope networking, SNA, OSI, X.25 and TCP/IP based networks

Software implementation and maintenance for the Unisys proprietary Uniscope network at the Wanganui Computer Centre, in support of the Unisys 2200 environment for the New Zealand Law Enforcement systems at the Wanganui Computer Centre.

COBOL batch and transaction programming on Unisys 2200 systems, primarily for the New Zealand Justice Department National Fines Enforcement system implemented on the Law Enforcement systems at the Wanganui Computer Centre.

Running a Xenix based Library issues system loosely coupled to the Council Burroughs B1800/B1900 systems. EDP liaison role between the Library and Council IT department for issues related to the On-line catalogue and other library systems running on the Council B1800/B1900 systems.
