WATSON/AASP
Senior Java Developer
(Feb 2008 – Till date)
WATSON is a web based system that automates the end-to-end activation process for new customers.
Its main target user groups are the indirect and direct dealers. WATSON is password protected, webbased application with credit history verification, account maintenance, and payment processing
functions. Main goals of this application are Activation of users( Entering customer information, credit
check, provisioning) and authentication gateway for other applications of T-mobile (CAM,POS,SAP
online etc.)
Environment:Java, J2EE, Struts,Hibernate3, Oracle 9i, JUnit, DBUnit, Eclipse, Pl/sql
Developer, Weblogic8.1,SAP connectors
Frameworks and Design Patterns employed:App-Layer: Session Facade, Hibernate for persistence layer implementation.
UI-Layer: Most popular MVC (Model-View-Controller) Architecture has been a de-facto
standard for the JSP based UI development using Jakarta Struts (an MVC framework.), Business
delegate, Singleton etc.
Contribution:
Added a product called Minute Allowance to WATSON. This new product will allow Customers to
manage lines on Family and Multi-line plans using limits and additional features to control the lines on
the account. EIT will provide servicing for this offering and Engineering’s Intelligent Network (IN) will
provide call and message controlling. Watson will be modified to include the ability to add the Family
Allowances feature at the BAN level for a new activation on a multi-line account (i.e., pooled and nonpooled accounts). Customers will be able to designate a Parent subscriber line via Watson after all of
the MSISDNs are activated and known. Other subscriber lines on the same account as the Parent will
be considered “Managed” subscriber lines. In the event that the Parent line is not set, a Watson user
must be able to end the transaction without a call to Care.
Added a product called RJ11 Platinum3. The goal of this project is modify WATSON, to allow users to
select a line that receives SMS notification for their port in request. When user selects port in request
WATSON must show a new page (Notifications page) with all the lines on that account and user must
select a line to receive SMS notification. Watson will assume first line will be selected if user does not
select any line.

Role:
Systems Analyst and Designer

Persona is a flexible, secure, smart card based database system developed for platform seven, UK.
Persona allows data relating to individuals and other entities to be held on smart cards and Internet
host systems under the protection of a flexible access control mechanism. Data Originators set up
Internet host systems called Data Publication Systems (DPSs) on which they publish persona customer
data. As Card Issuers, they also issue customer smart cards on which they have loaded some of the
data from their DPSs. The data on each DPS is maintained by its Data Originator. The DPSs may be
remotely accessed and data downloaded from time-to-time onto customer cards. Acceptors provide
goods and services to customers by interrogating with their Acceptor Systems the data on the
customers’ cards and on the DPSs. A program on a smart card provides the means whereby an
Acceptor System can access the data required. An Acceptor can be assured of the authenticity of a
customer’s Identification data because of the vetting performed by the Card Issuer.
