PROJECT DETAILS

Deutsch Bank Bangalore, India Oct 2006– Jun 2007

Security Pass Authorization Request Solution

Software Developer

This system was built to automate access card application process submitted to the security division. The manual

process was tedious and time consuming. SPARS was built to cater the above problem by making the request

and approval through web based application. Here once the user submitted the request, the application would

find a workflow scenario for the submitted request. The requests would be updated to pending status and email

notification would be sent across to approvers. Once a request has been approved by all the levels of approver

then Pass Admin Office will update the status of request and pass will be issued.

Roles & Responsibilities

Part of the team involved in the business requirement gathering and evaluation with the client.

Responsible for the helping other team member(s) to understand the business domain and technical

requirement of the system.

Understanding the module level functional requirements.

Developed the front-end web presentation layer using HTML, JSP.

Involved in the designing and developing multiple modules of the application using Java, Servlets.

Developed Hibernate classes for data retrieval from Database

Involved in writing SQL queries.

Extensively used Eclipse IDE for Development.

Responsible for unit testing and integration testing, bugs fixing, handling change requests and code reviews.

Implemented the build process using Ant.

Involved in development of user management module.

Involved in writing the user guide.

Environment

Java 1.5, J2EE, JSP, Struts, JavaScript, HTML, XML, Eclipse IDE 1.6, Weblogic, Oracle 10G, Hibernate,

VSS.

Ameriprise Financials Bangalore, India Oct 2005 – Sep 2006

Knowledge Management System

Software Developer

Was involved in developing Knowledge Management System (KMS) for Ameriprise Financial Systems. This was

a knowledge portal designed for internal use for the Employees and Advisors. KMS is web based and developed

using J2EE technology - JSP, Servlets and JDBC following Struts framework on Weblogic application server. This

facilitated in corporate training and tracking the performance of trainees. This application incorporated features

such as content management, enrollment, e-notification and performance evaluation.

Roles & Responsibilities

ACADEMIC PROJECTS

Simple Stateful Network File Server (SSNFS):

Designed and implemented a Simple Stateful Network File Server (SSNFS) that supports remote file service

model in Java. The server provided for handling multiple clients. It implemented session concepts to keep

track of duplicate requests for client. The messages from client and server had specific format. Socket

programming concepts (instead of RMI were used) in Java. Error handling for incorrect message format,

incorrect message sequence, and invalid sessions were incorporated into the server side program.

The client program provided for a simple interface for the user to initiate a transaction build a message and

communicate with the server.

The server had the ability to recover from a crash and keep track of unfinished transaction and take proper

action.

The implementation was in Java.

Bibliographic Information System (Bibs):

Implemented a Bibliographic Information System (Bibs). This Project implements all the basic features of

Bibs. It provided for features such as to upload data to remote server as well as download data from remote

server. It also implemented features for searching the database based on input criteria’s specified by users.

The interface was designed using JSP. Validations such as type checking were also incorporated. Features

such as user authentication and data validation were also provided for. Parsing input file for extraction of data

as well as converting input data into bib format were also taken care in the implementation of this project.

This project was developed in Java, Swing, and Oracle.

Software Implementation of Pipelines:

This project was a simulation of pipeline of MIPS architecture. The objective of the project was to simulate the

execution of instructions in 5-stage pipeline. It also incorporated the score boarding technique. It incorporated

features such as caching. The implementation was for write back cache. It generated log file to trace the

sequence of instructions executed along with the data values in memory and cache. LRU replacement technique

was used caches.

It was implemented using Java.

Implementation of BitTorrent:

This project was partial implementation of the existing Bit Torrent. It implemented all the important features of Bit

Torrent such preferred neighbor concepts as well as optimistic unchoking, choking.

The application was developed using Java.

Implementation Traveling Salesman Problem (Dynamic Branch and Bound Technique):

Here the goal was to find the minimum path for a tour starting from any city as the starting point. This concept

was implemented using the data structure linked list (the static version was implemented using the concept of

tree). The input to the program was a Cost Matrix. Initial processing of the cost matrix was done to obtain

reduced cost matrix.

Every time the path along a particular node is expanded its cost (cost of the edge from the previous node to

current node is added to the reduced cost matrix) called the expected c value is maintained. Once we expanded

a particular path completely we set this c value as the minimum path. Now we look at unexpanded nodes (paths

which have not been explored completely) to check if a particular path will give us a feasible solution (that is its c

value is less than or equal to the existing Minimum value), if this is the case we explore the current path to obtain

c value and see if it is the new minimum value. On the other hand if the c value of a particular node is greater

than the current minimum c value it is not expanded.

Implemented in Java.
