Project: FOCUS

Financial online claim utility system enables HP to pay its business

partners, the promised reward amounts for the sales they perform. When a

sale is performed by the vendors there will be a monitory benefit for the

higher volume of sales. The monitory benefit will be paid to the vendor

using an automated process. FOCUS enables the user to key in the payment

data and waits for the approver to approve the payment. Once the payment is

authorized an EDI file will be generated. The EDI file is generated on the

SPS environment and using HP enterprise service bus the files are sent to

downstream systems so the vendor gets paid by HP.

Project # 7:

Hewlett-Packard, India

Jan 08-Mar08

Java/J2EE Developer

Project: Shared Portal Platform

Shared Portal Platform the proposed platform makes use of widely accepted

standards (WSRP and more generically, web services), solves many common

problems once through the Common Web Services, and takes advantage of

vendor solutions without a tight coupling that binds HP to a particular

piece long term. At its highest level of integration, content providers

communicate with the Portal Server using the widely used industry standard

Web Service for Remote Portlets (WSRP) protocol. When needed, the

individual portlets communicate with the Common Web Services, primarily to

gain access to the group/user profiling so that they may provide portlet-

level authorization and customization. These portlets also communicate

with their functionality-specific back end data stores (not shown here).

The use of WSRP enables the different portlets to deploy independent of one

another.

Responsibilities:

o Developed the JMX components to monitor the weblogic server data.

o Monitoring the web server performance to identify server peak

performance and to fine tune the configuration to scale the server to

higher performances.

o Collecting the metrics data from the production environment and use

the data for analysis.

o Developed portlet to consume WSRP.

o Debugging the existing portlet code and fixing the critical issues

reported by the end user with in no delay.

Environment: Java, J2EE, Vignette, Oracle, Linux, Web logic, Clearcase,

Log4j, ANT.
