- Jul 2000 Component Framework using EJB (CUE); MET Life, Warwick, Rhode Island Senior Java Programmer

The Object Technology Group is a core technology group of Tata Infotech, which is responsible for providing leading-edge object technology solutions for the vertical market segments. The Application Framework project of Tata Infotech leverages the core competencies in object technology to provide a generic N-tier architecture for developing business applications including ECommerce and EBusiness. In addition to the architecture, the application framework provides a host of services along with the range of pre-built and pre-tested components, which can be utilized for developing enterprise class business applications by building plug-in application specific vertical components. The engineering design utilizes the abstract factory design pattern along with Rational set of Case tools for platform independence and optimal reuse of the framework components.

Component-framework Using EJB or CUE is the J2EE (Java 2 Enterprise Edition) version of the aforesaid application framework in which the components are built as per Enterprise Java Beans (EJB) version 1.1 specifications using 100% Pure Java. In addition to the generic services and reusable EJB components, CUE provides easy interfaces to integrate existing CORBA and non-EJB components as well as a base application structure with EJB-based middle-tier, JSP based front-end for browser access and a host of back-end options including Object DBMS and RDBMS. Although the current version of CUE is being qualified for the IBM WebSphere Advanced Application server, it can run on any application server, which supports EJB version 1.1 container specifications.

Object modelling and design has been done using Unified Modified Language (UML) and Rational Rose tools. Business logic resides in Enterprise Java Beans (EJB) deployed on WebSphere Advanced Application Server. XML has been used for coding the deployment descriptors of EJBs.

As a Senior Programmer, was responsible for the following:

Requirement Study/Definition.

Identification and defining the functional specifications for the EJB components such as security, alerts, and error handling, correspondence and other basic services and interfaces.

Assisting the Technical Architect in designing and object modelling of the application.

Use Case Analysis and Design

- Nov 1998Disclosure Filing System for Tata Infotech Ltd., Noida Programmer Analyst

The Disclosure Filing Framework was an offset of the House Bill 2611 launched across the USA. The bill makes it mandatory for all states to:

Have a Web-based application for disclosure filing by election candidates.

Enable the general public to make queries to check the details of particular election candidates.

The Disclosure Filing Framework can be broken down into two components:

Candidate Accounting Software (CAS) Stand Alone Component

The CAS module enables election candidates to update and monitor the details of their campaign finances on a day-to-day basis. It allows them to monitor the amount of funds that they receive from various sources and keep track of the expenditures they incur during their campaign period. This module was developed using Java as the front-end and MS-Access as the database.

On-Line Disclosure Filing (ODF) Web Based Component

The ODF module enables candidates to file their final consolidated forms available on the Ethic Commissions web site. It also allows the general public to make queries to check the details of particular candidates. This module was developed using a logical three-tier architecture with the application logic being taken care of by the middleware that was developed using Servlets. The front-end for this component comprised of HTML forms & the back-end was an Oracle 8 Database.

As a Programmer Analyst, was responsible for the following:

Programming using AWT, JDBC and SQL to develop front-end for the CAS module.
