Summary:
My objective is to pursue a software/systems/network engineer position. I have
years of experience developing software under UNIX & Windows environment. As
a senior software engineer and systems engineer for the past several years, I worked
in areas of global network architecture design, UNIX/Windows system
administration automation, Internet traffic monitoring/reporting, customer web site
design, computer security, storage area network (SAN) design, and storage systems.
Computer Skills:
Programming Languages:
Operation System:
Assembly for MIPS and 80x86, MPI Parallel, Basic,
Fortran, Pascal, Ada, C, C++, Java, HTML, ASP,
JSP, Tcl/Tk, shell scripting, Perl, SQL
Unix (Generic, Linux, Solaris, and SGI IRIX) and
Windows NT/2000
Work & Research Experience:
Senior Systems & Network Engineer: SageMetrics Corporation, North Hollywood,
CA
July 2003—Present

Develop Unix-based application to collect, download and process web logs
using C and Perl. Implement operational tools to support and monitor
computer, security, network and storage infrastructure.

Provide on-call second-level support and problem resolution for the Network
Operations Center. Perform routine operational duties related to backups, data
loads, software updates, configuration changes
Senior Software Engineer: Exodus, a Cable & Wireless Service, Marina del Rey,
CA
Apr. 2000—July 2002

Wrote scripts to automate general UNIX/Windows system administration
tasks. Designed OS (Windows/Linux) packages to automatically build a
customer server from scratch.

Developed Internet traffic monitoring and reporting software under UNIX
environment. Developed customer portal for traffic monitoring and reporting
in real-time using Java Servlets. Used both Perl and Java to communicate with
the backend SQL database server.

Worked on areas of centralized logging and computer security. Wrote scripts
to secure Unix and Windows servers (both hardening and intrusion detection).
Modified SSH (secure shell) package to allow users to be authenticated using
token-generated dynamic password.

Designed reliable global network with low latency and quick response,
configured Cisco routers, and Foundry switches. Designed Storage Area
Network (SAN) and researched on Fibre Channel technology.
Research Assistant & PostDoc: Dept. of Earth & Space Sciences, University of
California, Los Angeles, CA
Sept. 1995—June 2003

Used parallel supercomputers and Beowulf Clusters to simulate convective
processes in the Earth’s mantle. Had experience working on IBM SP,
Paragon, Cray T3E and T90 at SDSC (San Diego supercomputer center).
Performed 2-D & 3-D data processing & visualization on SGI workstations.
Research/Teaching Assistant: Dept. of Computer Science, University of California,
Los Angeles, CA
Jan. 1999—Mar. 2000

Performed parallel simulation of computation and communication-intensive
programs. Predict execution time, scalability, and sensitivity to interconnection latency on distributed memory machine IBM SP2.

Developed I/O intensive parallel scientific applications. Studied the behavior
of applications based on communication latency, the number of available
processors on the architecture of interest, different parallel I/O caching
strategies, and parallel file system.

Taught course: Computer System Architecture (Apr. 1999—Mar. 2000)
Research/Teaching Assistant: Peking University, Beijing, China
1992 – 1995

Numerically modeled the evolution history of an oil-rich South China Sea
basin using finite element method. Taught course: Solid Mechanics (Feb.
1993—July 1993)
