Bank of America is one of the world's largest financial institutions,
serving individual consumers, small and middle market businesses and large
corporations with a full range of banking, investing, asset management and
other financial and risk-management products and services. JavaRelay a
GWIM, also known as Private Bank application deals with high Net worth
clients.
JavaRelay acts as a real-time Java middleware between CED (Core Entity
Database) and others private bank applications. There are 4 private bank
applications which JavaRelay supports as a middle ware.
1. CMO-CED Integration outgoing: This is a plain java application which
acts as middleware between CMO-Client Management Online (Siebel
application) and CED. It helps the bank associates to raise requests to the
CED for modifying client profiles and creating new clients. Request are
accepted from CMO and sent to CED through web service calls.
2. CMO-CED Integration Incoming: This is a java application which updates
the Private Bank with the changes happening on CED. Messages containing the
changes are published to an MQ and the java application takes the message
and processes it by converting it to java objects. Processed java objects
are converted back to xml and put in another queue to be consumed by the
private bank.
3. CED Lookup: This a client server application deployed on a web logic
server.Based on the search criteria given by private bank web service calls
are made to CED to retrieve the data.
4. PFG -CED Integration: This is java application that acts as a middleware
between CED and the referral database. Here required details are accessed
from the messages (published by CED) taken from a queue and web service
calls are made to update the referral database with these details.

methods are used to authenticate. Using two factors as opposed to one
delivers a higher level of authentication assurance. The project provides a
solution for Phishing and Pharming attacks where the attempt to
fraudulently acquire sensitive information, such as usernames, passwords
and credit card details, by masquerading as a trustworthy entity in an
electronic communication. Phishing is typically carried out by email or
instant messaging, and often directs users to give details at a website,
although phone contact has been used as well. This application seamlessly
authenticates users from a range of open multifactor options to address
identified risk

Jr. Software Developer
Maintain the client/server application framework based on the model-view-
controller (MVC) design paradigm. This application processes on any JSP
and JavaScript-enabled browser. Typically, the client sends HTTP requests
to the servers that act as the controller of the entire application. The
Servlets, along with the server components, perform the necessary business
logic needed, query the Oracle database and store the data in session in
the form of Java Beans. The presentation layer consists of JSP pages,
which use the Beans and generate HTML pages that are returned to the
browser making the system lightweight and presenting quick responses to the
user.
Responsibilities:
. Designing the system using UML methodology. Modeling the system using
Use Case Diagrams, Conceptual Diagrams, Sequence Diagrams,
Collaboration Diagrams and Class Diagrams.
. Developed GUI using HTML, JavaScript, and JSP.
. Developed modules in Java with embedded SQL queries for transactional
processing.
. Coded Dynamic content generation using JSP and Servlets.
. Client side validations were written using JavaScript.
. Developed stored procedures for use in the entity beans using PL/SQL
for the database insert and update of vendor information.
. Programmed XML/XSL data and in/out streams' processing's for SQL
Server transactions.
. Involved in table normalization, populating data using SQL Loader,
writing complex queries, data formatting and writing triggers.
. Wrote several DTD's and XML Schemas and used XML parsers for data
portability across Application layer and backend systems.
. Used Sax parsing methodology for serializing and parsing the XML
request and response
