Training
Summary
In late 1995 and early 1996, I helped maintain a network of
workstations and Xterminals for the Applied Mathematics department at
the University of Washington. I became a systems administrator
supporting terabyte-scale Sequent servers for Boeing Information and
Support Services in the Fall of 1996 and became the lead administrator
for a team within the same group at the beginning of 1997. Along with
my duties as a lead administrator, I played an important role in the
certification of three new technologies for use at Boeing and helped
implement the technologies after certification was complete.
Throughout 2001, I was a primary resource for Linux/UNIX systems
design and support and computer security for a network consisting of
approximately 200 machines at a bioinformatics firm. In this
capacity, I designed and implemented firewalls, was a main designer of
the procedure for automatically reproducing the company's primary
bioinformatic product, and performed all of the routine tasks of a
systems administrator.
Since the Fall of 1995, I have performed most of my research on Linux
systems that I maintain. I have performed the full spectrum of
administrative tasks and have done considerable software development
under Linux.
I have maintained several Microsoft Windows systems, from Windows 3.0
through XP. I have developed software under Windows 95 and 98, have
solved problems under Windows, and have performed many hardware and
software installations, updates, and reconfigurations. In particular,
I performed extensive Y2K remediation, prior to January 1, 2000, on
several machines running Windows 95 and 98.
Experience
Computational Scientist
Integrated Genomics, Inc.
2001
As part of this position, I was a primary resource for Linux/UNIX
systems design and support and computer security. At the time, the
computing resources at Integrated Genomics consisted of approximately
200 machines running Linux, FreeBSD, OpenBSD, and a variety of
Microsoft operating systems. In this capacity, I
- Designed and implemented firewalls to stop crippling attacks.
- Was one of two primary developers of the procedure for quickly
reproducing our primary bioinformatic product. This procedure
replaced a several-day-long, error-prone, manual process with
an automatic process taking less than an hour.
- Designed, built, and installed systems.
- Installed and replaced hardware.
- Installed and updated software.
- Built custom kernels and upgraded BIOS software.
- Performed backups.
- Monitored systems for performance and security.
- Assisted users and other administrators.
- Solved problems.
- Wrote perl and bash scripts to support all of the above activities.
Linux Systems Administrator
I have installed and maintained several Linux systems that I have used
for most of my scientific research, the systems at Integrated Genomics
that I described above, as well as miscellaneous Linux systems at
Boeing.
1995 - present
- Installed and configured
- Red Hat Linux 2.x - 7.x,
- Slackware Linux 4.x,
- Mandrake Linux 6.x - 8.x.
as the sole OS or in dual boot configurations with Windows 95, 98,
ME, and 2000 on desktop and notebook/laptop computers.
- Patched, configured, and compiled kernels in the 1.2.x, 2.0.x,
2.2.x, and 2.4.x series to support the particular hardware of
specific systems and to increase security and performance.
- Benchmarked network performance for ethernet and PLIP and
optimized NFS.
- Created Bash and Perl scripts for administrative tasks, including
a Perl module for transfering directory trees using FTP, which I used
to perform nightly backups of my scientific work over a dial-up connection.
- Performed BIOS upgrades and extensive hardware work, including
- Adding memory and replacing defective memory.
- Adding hard drives and replacing defective hard drives.
- Installing hard drive controller boards, modems,
and ethernet cards.
- Copying systems to new hard drives.
- Processor upgrades.
- Fan replacement.
- Floppy and CD drive replacement.
- Extensive hardware and software configuration and troubleshooting.
- Constructed PLIP and ethernet networks.

for maintaining 8 Sequent Symmetry 5000 data servers, including
a two-node cluster, and 1 Sequent NUMA-Q 2000 data server.
- Resolved procedural disputes between my team and other teams of
administrators that originated with my predecessor. This improved cohesion
within my group and increased the respect accorded to my team.
- Helped resolve disputes and misunderstandings and improve the
relationship between my group and the database administration group.
- Helped create activity schedules in cooperation with upper management.
- Helped assess hardware, software, processes, and procedures in
cooperation with other technical leads and technical services personnel.

of 8 administrators and technical services personnel in certifying
the NUMA-Q 2000 hardware, Dynix/ptx 4.4.x, and SVM 2.0.x. This involved
setting up, maintaining, and testing 5 NUMA-Q 2000 systems, including
a two-node cluster, connected to one or more 868 GB EMC Symmetrix 3430
storage devices and STK 9710 tape libraries.
- Planned the upgrade of 3 terabyte-scale Symmetry 5000 data servers
from ptx 4.1.4 to ptx 4.4.1 and led my team in performing this task.
