Project work
Organization: Vistaar Inc.
 Data Area Service
The goal was to create multi-treaded CORBA service, which allows in-memory OLAP cube
data stored in the another distributed service of the product, Vistaar Solution, in the oracle
database. It will be the replacement of the current file-based storing of data in various OLAP
cubes.
Technologies: C++ on Linux, enhanced SQLAPI++ library, CORBA
Role: I was involved in analysing the requirements, designing idl for the service,
designing object-oriented solution, coding the solution and creating test plans for
unit testing, integration testing and system testing.
Project Duration: July 2006 – Till date
 Enhancing SQLAPI++ Library
The goal was to enhance SQLAPI++ library, third party database independent API in C++, to
support bulk mode updation/insertion/deletion to the underlying database and supporting
additional datatypes like 64 bit integers and null terminated strings in an optimized way.
Technologies: C++ on Linux, OCI for Oracle and SQLAPI++ library
Role: I was involved in analysing the library and the bulk-mode support in DBMSs currently
supported by the library; Designing developer level APIs for bulk mode support which
should be independent of the native bulk-mode support in DBMSs; designing objectoriented solution to implement developer APIs such that it is not only resilient to future
changes in the library and flexible to incorporate the bulk-mode support in the DBMSs
(which are currently doesn’t support it natively) with minimal code changes; coding the
solution and testing the library.
Project Duration: June 2006 – July 2006
Organization: C-DAC Mumbai (Formerly NCST)
 Vidwan: a Web-based Expert System Shell
The goal of the system is to develop an expert system shell, which allows creation of a
number of expert systems. Each expert system consists of set of rules, encoded by knowledge
engineer, trying to emulate an expert. The system support three kinds of users:
RulebaseOwner, RulebaseUser and RulebaseAdmin.
Technologies: Java, JavaServlet, JSP, PostgreSQL 7.3, Apache Jakarta 5.5
Role: Project Leader. Lead a team of three developers, analyzing the system, designing the

Project Duration: September 2005 – April 2006
 Mulyaankan: A Fraud Detection System
A client-server system for analyzing national importers data collected from 529 custom
houses of India. The analysis of the data finds out the frauds in imported cases and generates
report based on it. It also helps custom houses in clearing imported goods of by viewing at the
previously analyzed data.
