Quality Data Loader Framework:
Responsibility includes as a development lead architecture, design and development tasks of an Extract Transform Load (ETL) application that will roughly process on an average 1,000,000 files a day. Data will be collected from sites that are geographically distributed all over the world. The project will be a SOA based distributed high performing system. The system will re-use old legacy Java code base with a newer SOA based system code, infrastructure and tools. The project is scheduled to utilize TIBCO EMS (JMS), TIBCO BusinessWorks (Orchestration), Java, JEE, JDBC, JBoss, JQuery, Spring, and XML.

GADSC China:
Responsibility includes coordination tasks between 15+ offshore software designers/developers and project stake holders in the USA. Duties includes management of resource allocation between 4 to 5 projects, mentoring junior developers, providing HP Global Architecture guidelines, providing design directions, and providing technical help.

Web GUI Administration for SIT Applications Framework:
Responsibility included architecture, design and development tasks of a Web Application to manage configuration information for various HP’s Imaging and Printing Group’s factory systems. The pilot phase will enable a legacy system called Virtual Factory System managed and maintained through a modern Web interface. The project will reduce cost of operation for IPG by enabling level 1 and 2 support personnel to trouble shoot and maintain server applications. The project will also increase efficiency by leveraging a single Web interface to manage multiple legacy systems which used to require multiple groups of support engineers to maintain. The project is utilizing Java, Spring, iBatis, Javascript, JDBC, Weblogic, Javascript, JQuery, JSON and XML.

FA OMR Start Stop Pipeline Utility Application:
This small utility application increased productivity of support engineers for database synchronization tasks between DBMS systems geographically located in different parts of HP’s Global IT infrastructure. The project is utilizing technologies like Java, Tomcat, Google Web Toolkit (GWT), JAX-RS Jersey, Google Guice, JDBC, Apache Commons DbUtils, XML, HTML, CSS, and Javascript.
