Description: As a member of the FTTP/vBuild team, responsible for maintaining and enhancing two tiered database application. This involved JSP/struts in the front end and EJB in the middle tier. Another part of the application is maintenance of the data loader application which pulls data from multiple legacy databases and populates the vbuild database. A prototype was developed using Hibernate to stream line the data loader program. Built a common login screen to use SSO (Single Sign on) feature. Then a complex project was started to convert the database to next version with lots of added features and integration to another application named vSchedule which was built using Weblogic Workshop. Built a detailed functionality of sending email notification when any roadblock was created for this scheduling application. After this, architected and developed a complex system for the FITS application where a complex xml specification was shown using XSLT and saved in DB2 database. Also used Castor to process xml data.

April, 2003 – June, 2004 (EDS Inc/Veterans Administration, St. Petersburg, FL):
Description: As team lead for the re-engineering project for the Clinical procedure in Department of Veterans Administration, was responsible for design and development of very complex medical application from Mumps and Delphi based program to Java and Oracle platform. At first a prototype application was built to gain familiarity with their legacy system and hl7 messaging protocol. We used Jsp/struts in the front end and oracle in the back end for this. After this, an analysis effort was started of the whole application. The result of the analysis was described in UML diagrams using Rational Rose. We developed the first iteration for the software which will include patient search, looking up orders for a patient, checking-in for a procedure, handling data from instruments in Hl7 format, and submitting a medical report. The back end was a legacy system written in Mumps to which a connection is maintained using J2EE connector architecture. The front end was developed by Jsp/Struts in the, Enterprise Java Beans(EJB) in the middle tier and M and oracle in the back end. A very useful program was developed using XMLSax Parser that will parse output of invoked M routine. Format of this string response in described in a XML file which is then parsed to generate a Java object through XML beans. Another part of the application involved JMS and Message driven beans(MDB) to process messages coming from real instruments and update the M database in the back end. A swing application was developed to simulate sending of hl7 data to the JMS queue. The hl7 messages were transformed by applying xslt pattern.

Jan, 2002 – Mar, 2003 (EDS Inc, Fort Worth, TX):
Description: As team lead of the ECDB project for American Airline as a Enterprise Java Beans (EJB) developer. Made some of the read only EJBs with fail over capable. This involved extensive testing with the java debugger. This work also involved production support. Extensively modified an existing monitoring program to help the on call staff. Modifications included detecting database hung state, ability to page certain errors while email others. This program involved extensive use of thread programming. Also developed a comprehensive swing application to check into the database in production. Since this database was getting constant feed from the mainframe, it was necessary to see if the feed process was alive or stopped. This solved the problem of checking into database manually. Another task was to convert a set of stateless session EJBs to commandpattern. Part of this task included writing a code generator program to generate more than 150 input output classes using XML and DOM parser. Later used XSLT to produce all the source codes. This program saved the project more than three hundred hours or manual labor. We were also responsible for production support for which we used Toad to manipulate database tables.

Feb, 2001 - Dec, 2001 (Sabre/EDS Inc, Fort Worth, TX):
Description : As a member of the AA.com project for American Airlines, designed and developed EJBs to retrieve and update customer information.
Work also involved developing JSPs The EJBs we developed were wrapper EJBs
calling mainframe through Coolgen generated classes.
As a member of the M & E department for American Airlines, have been involved in maintenance and enhancement of a Java application which is used to track airline manuals. Also designed and developed another Java application to keep track of expired mechanics in Sabre. This program took long time and could be stopped and started any time. But this posed challenge because we had start exactly where we left off otherwise it will take unnecessary time and more charge to the account.
Was involved in the development of middle tier Java application in the AACORN project. For this Developed several stateless session EJBs. The business EJBs retrieved information from legacy Sabre system using host EJBs. Bluestone application server was used. In the design phase, Rational Rose was used to create class diagrams and interaction diagrams. These diagrams were created in UML notation.

Oct, 1999 – Feb, 2001 (Sabre, Dallas, TX):
Description : Was involved in the support, maintenance and enhancement of Canadian Airline’s reservation web site. This work involved working on all aspect of the application. This application was written in C++ and ran on UNIX platform. A very useful Java application was developed to ping the website to check that it is up and running. Several Perl scripts were written to gather statistics to from log files. The project ended because Canadian merged with Air Canada. For this merger, had to develop and scheme by which Canadian could still log on to the Canadian web site but then were redirected to the Air Canada web site for booking activities but remained in our web site to get mileage information. This scenario worked until they completed the merger and the web site was shut down.
