Job Title: Web Application Programer
A website application is designed to teach college educators to adapt certain software for administration. (detail is NDA)
This is the largest web app project I have done as a single-person project. Tech used: PHP, MySQL, JavaScript + CSS2, Linux, Apache. 90 PHP pages, 8311 lines of code, 10 database tables.
A small-scale e-store. The site features shopper login, credit card transaction, admin login, inventory.
This is a legacy project from a previous programer. The project had zero documentation. 3420 lines of Perl in just 2 files, and 60 ad-hoc XML template files, and uses plain CGI. It uses MySQL, and is hosted on Linux running Apache.
This is a very small-scale eBay-like auction site. There are a total of 35 files written in PHP and MySQL. Hosted on Linux running Apache.

Job Title: Consultant
Worked for Professor Richard Palais on the project 3D-XplorMath, supported by a grant from National Science Foundation.
Built a web site with Java applet that shows mathematical surfaces with interactive rotation. (http://virtualmathmuseum.org/) This website has 580 HTML pages, with Java applets for interactive 3D rotation of 400 math surfaces and other visualizations. e.g.: Plane Curves, Space Curves, Conformal Maps, Fractals, Surfaces, Polyhedra, Ordinary Differential Equations.
Tech used: Mac OS X Server, Apache, Java, perl, LaTeX, PDF.

Job Title: Software Engineer
Programer of Netopia's enterprise eCommerce Server. Team of 5.
This is a typical enterprise level e-store system. Similar in scale and features to Yahoo's e-store. It runs on Solaris and HP-UX. Features includes i18n, credit card processing, customizable store appearance, web based inventory control, sales report and traffic report, discount or special pricing system, international tax and shipping charges calculation system, etc.
The technology used that I had a major part are: Apache/Stronghold webserver, Apache JServe (Tomcat precursor), an (in-house) application server (in Perl). The system also uses (in-house) Java Routing Servelets, and Oracle Database.
I was responsible for sys admin over in-house development machines (several Solaris and HP servers), managing CVS and code branch merging, and as a programer to critical parts of the system, including credit card processing back engine (with CyberCash, LinkPoint), online order interface and processor, integrating the 4 server components to communicate, decision on a new server engine (Resin, iPlanet), writing installers, writing diagnose software, and design and implement the upgrade driver system.
I was the primary person responsible for installing (or help clients or co-workers in staging department), to install, upgrade, or test, the complex server software. (except for the oracle database. That was handled by a dedicated database admin.)
Our customers include Verizon.com and several high-volume e-store hosting service providers. As an example of the system's scale, one client has 40 thousand stores, with Oracle data file over 4 tera bytes.
Date: December 1998 to July 1999
Job Title: Senior Software Engineer
I am part of a startup team of 7. Our company is a job hub ( brainpower.com ), in competition to dice.com and monster.com.
We have 3 engineers, counting myself. Our engine includes web interface, resume database, jobs agents and seeker agents, mass mailing subscription system, and internal bug database.
Among other things, I wrote a bug database for internal use. The software is one single file in Perl, 4k lines. It uses MySQL for database and CGI.
Date: February 1998 to April 1998
Job Title: Programer
Maintenance engineer for a small online escrow start-up. Duties include re-coding legacies systems, traffic analysis, and reports generation. Technology used were: Linux, Apache, miniSQL, and Perl.
Date: February 1998 to March 1998
Job Title: Consultant
Consultant for a classified project. The task is to create a geometric 3D model in Mathematica. The client traveled from NY to have a interview and sign a non-disclosure contract. My client is extremely satisfied by my work.
Date: January 1998 to February 1998
Job Title: Quality Assurance Engineer
Beta testing for a dynamic 3D graphics visualization software product based on OpenGL for Mathematica. (The product has been bought out by Wolfram Research.)

Date: June 1995 to December 1995
Job Title: Intern Programer
Student research intern. My task was to create a series of education and research material on plane curves (geometry). The material includes curve's history, definition, properties, applications, with a potential as a commercial add-on product. A significant part is to write a series of Mathematica program that allow systematic generation of proper animations for visual “proof”.
Master level (7+ years): Mathematica, Perl, emacs lisp, HTML5, CSS3.
Expert level (5+ years): Unix sys admin (Solaris, Mac OS X), PHP, Apache, MySQL, SQL, Second Life Linden Scripting Language.
