July 2002 to Aug 2011

Developed the ICOMS Web Service using Xerces to parse XML document. Use SAX parse as event based model to parse XML without value be need to store in memory, and use DOM parse to allowing larger XML files to be parsed within the DOM tree.

Developed and production support ICAPI - ICOMS Web Service API - the ICOMS billing solution is a cable billing system run at AS400, with client likes COX, Time Warner Cable, and DISH Network. This is a web services implement wrap Enterprise Java Beans (EJBs) which will wrap service Plain Old Java Objects (POJOs) which will call the ICOMS API Gateway, JDBC and or PCML to perform the business logic, it parses the XML through SAX in the DOM tree, and fetches to the billing system. It runs at JBoss and WebSphere application server.

Developed and production support NextGen PostPay Billing system with client likes AT&T, Metro PCS and Leap Wireless, xmlgateway solution implement Service-oriented architecture – with xml through TCP/IP, and the back end is interface with Oracle 10I running PL/SQL for airtime collection.

Implement the AJAX technology, to allow drop down from the custom web pages to be updated asynchronously by exchanging small amounts of data to the html control, hence, without refreshing the whole web page. The web server is located in Cincinnati US and the end user is in Taiwan East Asia.

Lead team of four contractors, one DBA.

Architect and develop the back end services for a Remote Activation Client system using MVC model 2 approaching, UML, Core Java, JSP, Servlet, EJBs, Struts, Spring, and Oracle. Prototype is built in ASP.net.

It provides a client server solution located on the SS7 network that acts as a node and functions as a serving HLR in specific activation scenarios. The solution provides wireless carriers a method of activating wireless devices using automated voice response or input through a WAP or Web session. With the addition of interfaces between the Interactive Voice Response solution and the wireless carrier’s billing system, a subscriber could proceed from an off-the-shelf purchase of an inactive wireless device to a fully provisioned, programmed and functioning device. The device could be activated in the network, billing, and customer care systems without any call center or other human intervention on the part of the carrier, thereby greatly reducing acquisition costs.

Lead team of ten engineers, one contractor, and one QA person.
