Network System Analyst
As a system administrator, I supported research, clinical, and business
supporting UNIX/Linux Systems, including a High Performance Compute (HPC)
Cluster which meets the requirements for listing on NSF grant
applications. This position encompassed all aspects
of UNIX support, from supporting hardware and building servers to
project participation and architectural decisions. This position

in an on-call paging rotation.
- Built and maintained a High Performance Computing (HPC) cluster
used by research users to solve resource intensive problems.
I managed cluster health, package/install additional
software for researchers, and managed accounts. The cluster consisted
of 87 compute nodes and supported over 30 software packages.
- Implemented a green strategy to power down unused compute nodes.
- Installed and maintained analytic tools for research,
including Matlab, R, and many bio-medical applications.
- Supported Linux, Solaris, and AIX clinical and research systems.
- Escalation point for all UNIX based applications
- Built a kickstart process sans DHCP/PXE boot for
network installs on networks which may not support DHCP.
- Primary for user access tasks.
- Primary support person for research users.

AIX's "mksysb" functionality using Mondo Rescue.
This process is used for disaster recovery and to
clone physical servers.
- Developed standard for out-of-band management of
commodity hardware with IPMI.
- Developed a process whereby Linux and MacOS systems
could seamlessly mount and access CIFS shares and DFS trees in
a secure fashion using Public/Private Keys for automated and
batch jobs. This included writing a specialized FUSE filesystem
to allow multiple users to access personalized mounts via the same
path.
Bank of America, from MBNA merger (Nov. 1999 - Jul. 2006)

- Audited scheduled jobs to ensure they were not
capable of negative side effects.
- Developed the UNIX-side automation to support an
entire Data Center migration to a different state, by finishing up
the work that staged hardware and SAN replicated disks could not. We
migrated our production processing in 4 hours, with nearly all
customer facing applications up at the end of the window.
- Created a data transfer and synchronization utility to
support data replication with incremental updates when
requirements were not met by existing tools.
- Developed a quality assurance system to verify system
configuration and standards compliance across all UNIX types.
This system is configurable and is used to verify system
compliance after all changes.
Application and Middleware Support Engineer
