Project Generic Application Generator (Cleveland Clinic Project)
Project Description:
This application is an application generator. It leverages XML in an ingenuous way to define metadata models for each aspect of an application -- even the data model the end user will work on. The primary need of the system is to be able to handle any user content or any structure, even one that has not been thought of yet. To achieve this degree of flexibility there has to be abstraction to the nth level. Hence, the system is about metadata and not user content. There are metadata for Screens (generates DHTML), Rules (business rules), Structure (attributes of user content), References (to populate and co-relate dependences) and Queries (query generator for reporting). The interplay of these XMLs with the user content XML data model generates an application without the need to code a single line.
Roles/Responsibilities:
• Reviewed and suggested alterations to the metadata models for Rules, References, Screens, and Structure to get the inter-relation and dependences correct.
• Architected the application. Designed the callback methods (flow of control) in order to have the correct sequence to load up the XMLs from Tamino and generate the application.
• Merged the Structure XML with the data XML matching the XPath in DOM with the corresponding attribute.
• Coded the basic infrastructure Java classes that can be extended to add code for each new business rule that needs to be included and implemented a few basic but important rules. The rules for each Screen element if mapped using XQuery.
• Architected a Tool that will help generate the metadata XML models so that the same can be free of human error and will adhere to the XML Schemas.

Project Navis Order and Rate Quote System

Project Description:
The application lets North American VanLines (nAL) accept inbound XML quotes from third parties and return an estimated cost to the user based on entered information. The XML document is first validated against a DTD and then based upon the Document Type; the appropriate Mediator Sequence is called. The customer then has the opportunity to book the shipment with nAL and that will be handled through a sales order entry process using a RossettaNet DTD. nAL receives Purchase Orders in XML format, which needs to be validated, transformed, and mapped to an Adabas database. The XML document is sent to a Java servlet, which makes an HTTP call to the Mediator. Mediator logs the incoming XML to Tamino database and identifies the sender and type of the document. The message will then be validated against rejection criteria. Based on validation results the mediator will either generate errors or perform required transformation to clean the XML file and then call the i2 Rate Quote System. The logged XML documents are the basis for tracking the entire flow. A Java based Audit application based on Struts framework is written to perform detailed queries on quotes, orders and errors.

Roles/Responsibilities:
• Develop mediator sequences which act as the control flow of the application and finally transforms and returns the result from the i2 rate quote system
• Define Tamino XML schemas used in the application
• Develop style sheets to do the required transformations
• Developed the Audit Application using the Struts Framework for the Navis Order and Rate Quote System
• Evaluated the effort to render the application as a Web Service

Project Supply Chain and Planning Optimization (*SCPO) -- Release -- 7.0
Statistical Exception Graphs in Networks Demand (Forecasting)
Project Description:
NetWORKS Demand? acts as an early-warning system, predicting future customer demand, alerting of potential supply problems, and finding patterns undetected by traditional solutions.
The Exception Graphs plot those Demand Forecast Units (DFUs) which do not fall within a certain range of the average forecast. These points in the graph help determine if the product or market combinations are changing. The 5 types of graphs are Forecast Quality, Forecast/History (Filter of Demand), Early Warning Signal, Trend Type and Trend Change.
These graphs are interactive over the web (created using Scalable Vector Graphics (SVG), a W3C standard). There are mouse-over events associated with each dynamically generated points and on clicking on a DFU point, the main Demand Forecast Application (Forecast Toolkit) is launched with the selected DFU's data so that the DFU can be further analyzed and forecast fine-tuned. The old point is still kept in session and can be viewed along with the new for better perspective of the impact of fine-tuning the forecast.
The application design and coding is as per the J2EE standards and is constructed along similar concepts as the Struts Framework. An EJB Session Bean accesses data through a DAO layer and converts it to an SVG XML DOM object which is then rendered as SVG output through a custom-tag in the JSP.
Roles/Responsibilities:
• Prepared the Implementation Specification based on the Functional Specification.
• Interactive graphs were used for the first time in Manugistics and was responsible for identifying which technology / product / plug-in would be most suited for our application. (Decided on SVG and Adobe's SVG Plug-in).
• This was a new feature with this release. Designed and coded the whole module including testing using JUnit testing suite.
• The application is built on Manugistics proprietary components called ViewPoint -- a model-view-controller architecture.
• Designed and coded the user views for property pages of this application.
• Any Vantive issues (product support) was also initially resolved by me.


Aug 2000- July 2001 NovaSoft Information Technology, NJ
Employer: NovaSoft Information Technology, NJ
Position Senior Developer
Client American International Group Inc. (AIG), New York, USA
Environment Java, EJB, Servlets, XML, XSL, XSL-FO, Documentum® (DFC API, Desktop Client, Intranet Client & WebPublisher), IBM Websphere, DB2, IBM Visual Age for Java.
Project Work Flow and Document Management System
Project Description:
Objective - To render three data intensive insurance documents over the web for viewing, editing and printing.
Architecture - The project design is based on the J2EE architecture and data transfer between any two layers is as XML objects. The business logic determines access as well as functional rights. The templates for the documents reside in Documentum®'s database called Docbase and are stored as XML files. EJB components query the database (DB2 and SQL Server) and return data as XML objects that are combined with the respective document-template-XML as well as user-entered-data (XML) and finally rendered into HTML by merging it with the appropriate XSL file. The HTML rendered Templates are also editable and the changed templates are saved into Documentum® as XML. The documents are made printable (with formatting and styling) by rendering into PDF format by FO objects. FO object are generated by XSL-FO processing.

Responsibilities --
• Developed a reusable interface for Documentum as a Stateful Session Bean (EJB) using Documentum Foundation Classes that can be used by other applications as well in AIG.
• Developed JSPs which are the starting points of the application and a Servlet which works as the execution controller for the whole application.
• Coded several Java classes used to manage the flow of execution of the project, such as data processing, task allocation, and session and I/O management.
• Made reusable EJB components that query the database (DB2 Version 7) and return dynamically generated XML objects for processing with XSL files.
• Coded XSL files (each for the three functionality of view, edit and print) with an extensive use of XSL, XSL: FO, CSS, HTML and JavaScript for rendering into HTML / PDF formats.
