Experience

Systems Engineer / Free Software Programmer December 2003 - June 2004

California Digital Corporation, Fremont, CA

Worked on team that built world's second fastest supercomputer cluster
for Lawrence Livermore National laboratory (LLNL). The system runs near
20 Teraflops, second only behind NEC's Earth simulator in Japan. It is
composed of 1024 systems each containing 4-1.4 GHz IA-64 CPU's and 8
Gigabytes of RAM totaling 8 Terabytes of memory. The systems are
interconnected via Quadrics Elan4 adapters and Gigabit Ethernet.

Debugged, implemented and automated various GNU cluster tools:
Free-IPMI, Powerman, biosconfig, pdsh.

Implemented LLNL's YACI cluster installer and debugged where necessary.
Contributed atomic image generation method.

Debugged kernel issues and methods for figuring out which memory modules
were bad, along with testing and debugging developers' code.

Wrote about thirty shell and PERL scripts to automate build, burn-in,
benchmark, and quality check processes.

Collectively built and ran Linpack benchmark on 64 system groups while
building cluster.

Developed ``Tracklog'' problem tracking system for diagnosing
problematic systems.

Developed GNU/Linux program for flashing Tiger 4 BIOS in Linux.

Implemented process for scalable unit verification and coordinated with
project manager and customer regarding quality check procedures.

Coordinated with vendors regarding issues on systems.

Placed in charge of Quality Control since project completion.

Built GNU/Linux imaging system along with various projects using
NFSRootBoot.

Skills Used: Free-IPMI, biosconfig, Tracklog, PERL, BASH, C, make,
Linpack, Cerberus burn-in, Debian GNU/Linux, Redhat , DHCP, tftpboot,
Cisco Catalyst 3500, Cyclades CAS, Quadrics. LLNL GPL tools.



Application Engineer / Programmer November 2000 - February 2003

WorldCom, Sacramento, CA

System and Application programming using primarily PERL along with bash,
ksh, PL/SQL, C, and Java on Solaris Unix and Linux.

Co-developed Universal Dial Up pool that supported multiple customers
through one universal block of modems. The Dial up pool utilized LDAP to
store users and make them available to the individual customers. The
SLAPD portion of LDAP replicated users to secondary facility for load
balancing and redundancy. Periodic jobs replicated the information in
RADIUS, which separated customers using the Dialed Number information.
Log data was parsed and converted into Oracle schema for querying.

Coordinated and released control of the Universal Dial Up pool from the
engineering group to Operations group. Gathered existing documentation
and created documentation where it was lacking.

Developed monitoring probes for the Universal Dial Up pool and
customized them to report to HP Openview. Implemented already HP
Openview monitoring methods where available.

Compiled and configured server applications. Apache, Tomcat, Wu-FTP.
Provided Apache expertise.

Maintained and diagnosed Opensales e-commerce application.

Diagnosed and debugged Oracle PL/SQL packages.

Implemented conversion process of scheduled jobs that performed
maintenance and produced reports for customers. Moved the code under CVS
control, replaced email reporting with HP Openview reporting. Created a
conversion procedure and coordinated with other programmers using Remedy
to track progress.

Created web based asset management application using PERL and Oracle to
track assets. This application allowed users to identify hardware,
locate it, track what electrical outlet to what it was hooked. It
correlated the jumpered connections through the server room as well.
Identified and specified what information needed to be tracked for
Point-to-Point, ATM, Frame Relay, and Dial circuits.


Skills Used: PERL, LDAP, RADIUS, HP Openview, Apache, Tomcat, Java,
Oracle, PL/SQL, CVS, Remedy, C, Solaris, Linux, rsync, tar, ssh, MS
Office, Visio




Programmer / Systems Analyst March 1998 - November 2000

Army Corps of Engineers, Sacramento, CA

Contractor through ITS Corporation and Maxim Group

Developed a custom financial management database using Oracle for
tracking the Total Environmental Restoration Contract (TERC) group's
cost plus fee contract plus interfaces to the Army Corps of Engineers'
(ACOE) accounting server called CEFMS on Windows, Linux and Solaris
Unix.

Developed reconciliation tool for correlating payments from CEFMS to
projects not stored in CEFMS using spreadsheet and a PERL program.

Developed Paradox graphical user interface (GUI) for users to input data
into the custom created database along with the capability to generate
reports that would come from either the CEFMS accounting database, the
custom TERC management database or both.

Prototype PERL/Tk GUI application for interfacing into the databases.

Developed advanced session maintaining CGI interface to the TERC and
CEFMS database. CGI application allows user to dynamically traverse data
along with maintaining stringent security standards. Used PERL to code
application along with Emacs and CVS for development and revision
control.

Provide occasional assistance to other divisions with computer needs.

Skills Used: Paradox, ObjectPAL, Oracle, PL/SQL, Apache, WinNT,
TeraTerm, CVS, PERL, PERL/Tk, Solaris, Word Perfect, Quattro Pro, MS
Office
