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 object-oriented 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 system, task allocation of the various sub-components to team members, monitoring the progress of the project and guiding team members during implementation and testing phase.

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.
