As Director of Operations for Broad Daylight Inc. I was responsible for all of the IT Teams including
Server Team, Network Engineering, Telecom and Help Desk. I was also responsible for Facilities. Under
my leadership, the Server and Network Engineering teams designed a completely new production system
for our web based application servers. This system consisted of fully redundant, highly available and
massively scaleable servers and routers at a Co-Lo site. The entire system is guaranteed to our customer
base to be available 99.999%. We used HP Open view and Site Scope to monitor out servers/web pages
and Legato clustering tools for server fail-over. Created policies and procedures for monitoring of systems.
I implemented a change control policy, a trouble call tracking system 7/24 server monitoring/paging
systems, a disaster recovery program and server build standards. Worked with vendors to develop RFP for
new phone system, designed to implement VOIP and ACD.(Not implemented due to dot.com financial
issues)

As Manager of the Server Team for UCSF Stanford Healthcare, I managed team tasks such as daily
maintenance of file servers, new projects including new server builds, server upgrades, domain
redesign, data migration, and change control.
Developed a strategic plan for integrating the better aspects of each network into a new Enterprise
infrastructure. Strategic plan included a reengineering of the North campus network that eliminated
dozens of small departmental servers as we moved the various departments to our Enterprise
servers. This reengineering process allowed a higher degree of support for the departmental users,
and saved the company over 2 million dollars by reducing the number of servers supported,
standardizing server builds and centralizing purchasing.
Strategic plan addressed issues such as the mixed environment of Unix/NT and Novell servers,
whereas each campus was predominately NT or Novell, the reengineered network used each Network
operating system for its strengths across the enterprise.

Integrated the two separate campus teams into one cohesive team of engineers that truly worked as a
team to accomplish our objectives. Nearly every project had an owner and at least 2 other engineers,
ensuring that we avoided the right hand-left hand issues and benefited from multiple points of view
as the projects evolved. An additional benefit of my ‘triads’ was that cross training was almost
automatic, as engineers were frequently assigned tasks to their weakness rather than to their
strength- something that cannot be successfully done when they work individually.
Consulted with various members other IT Management team, Doctors that headed up various
departments, and Executive Staff in the development of a formal Service Level Agreement. Many
of the departments had previously preferred to handle their own IT issues, but fully embraced my
plan to centralize support and standardize systems. Most servers would never be monitored, and
only after failure would they be serviced. With the Enterprise system, we monitored every server
constantly, and avoided most of the problems before they manifested.
Strategic plan addressed issues such as the mixed environment of Unix/NT and Novell servers,
whereas each campus was predominately NT or Novell, the reengineered network used each Network
operating system for its strengths across the enterprise. It also avoided the issues that would
inevitably arise if we attempted to eliminate one of the systems, as some of the engineers and some of
the users only knew, and thus swore by one or the other.
Rolled out a network performance monitoring system that allowed us to definitively point out a
network problem that caused out network utilization to get hammered. Without the monitoring in
place, the South campus suffered severe network utilization issues for over 90 days after Microsoft
SMS was deployed. When SMS was deployed on my network though, I was able to point to the exact
time of deployment and show on a graph as the utilization skyrocketed. SMS was turned off within
the hour and utilization dropped from 100% to 17%. It was this issue that prompted my promotion
to Enterprise Network Manager.
Maintained 100% retention of my team in the face of the merger, with cuts throughout the
organization, and the fear of layoffs throughout. My team had a clear mission, and through a metric
that I developed, knew exactly what their deliverables were, and how long it would take to do any of
the tasks involved. Management used my metrics to increase my staff as we took on support
responsibilities that extended out baseline service level enough to impact out level of service.
Shamrock Network Engineering, San Mateo, CA 4/94-10/97
Senior Network Engineer
Project Manager
Managed a Windows NT migration project at KLA Instruments involving 1350 PCs in a seven building
campus, from initial inventory through migration and follow up support and training. This project included
the hiring and managing of 24 contractors.
Managed a project at West Marine Products involving the migration of 284 PCs to a NetWare environment.
This project included hardware and software upgrades to meet standards, as well as installation of network
client and terminal emulation software for AS400 connectivity. Also provided initial Help Desk setup and
training.
Performed a Network Quality Assurance Audit for a local insurance company. This project involved
analyzing Windows NT servers for design, performance, fault tolerance, and back-up procedures. System
security (both internal and external) was addressed, in addition to host connectivity. Desktop
standardization, cabling, wiring closets, hubs, and router configurations were also analyzed. The end
document enabled the company to close existing security gaps and to improve the performance of their
network, maximizing the return on MIS investment.
Developed Network Documentation deliverables for a division of Wells Fargo, enabling MIS support
teams to provide more timely support to their users.
Supported a 15 server Novell 4.01 network in a development environment, and designed server and desktop
standards for a project to be rolled out to AAA field offices statewide. Issues addressed were security,
accessibility of software, NDS design, CD ROM enterprise access, DAT backup, desktop standardization,
and software version control.
