Company: Netopia, Inc.
Date: July 1999 to October 2002
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.
