Worked as project lead and architect and also developed extractor in C/C++.
Aug’01 – Jan’03
Data Mining Solution Kit
Data Mining Solution Kit brings data mining features to NonStop platform users. It consists of following products:
 Data Preparation Tool provides users ability to profile and prepare data for data mining
 Data Transfer Tool provides users ability to move data from NonStop tables to SAS datasets
 Data Modelling Tool moves models generated by SAS Enterprise Miner to NonStop tables for use in data
scoring during online data mining
Worked as architect and also developed components for Data Preparation Tool and Data Transfer Tool. Project
involved work in C/C++ and MS VB 6.0.
Nov’00 – Jul’01
BigFiles Enhancement of NonStop SQL/MP
Compaq Computers Corporation, Cupertino, CA
BigFiles enhancements, which were earlier made available in Enscribe, were extended to SQL/MP. With BigFiles
feature in place, users can create SQL/MP partitions of size up to 1TB. Many customers desired this feature as



Issue Information
Market Participant Information
Volumes of Issues Transacted
Statistical Information about an Issue in the form of Graphs and Reports
Blue-Sheets helps NASD-R in tracking fraud activities at NASDAQ. It takes care of:
 Cases generated against Market Participants
 Informing Market Participants about Frauds via Email


Taking care of the response made by the Market Participant through Data Integrity Reviews
Provides Analysts a way to maintain their own database (in the form of MS-Access) for easy tracking

Development of UMPT (Usage Massive Parallel Test)
Belgacom, Belgium
Belgacom (Telecommunication Company) opted for HP NonStop as solution for handling its increasing business.
The company as well as customers required comparison of revenue generated by old system (Siemens) and new
system.
UMPT was made for comparing the revenue calculated by the old system and the new system on day-to-day basis.
UMPT produced reports for customers and the company.

Web Based Netbatch-Plus
Netbatch is a powerful tool for time scheduling, start-up and management of the jobs on HP NonStop.
The objective of this project was to establish communication between the Internet Browsers and the existing
Netbatch Servers.
A Web Server was developed based on HTTP 1.0 protocol. NonStop Web Server used to service requests from Web
Clients (IE or Netscape Navigator). HTML equivalents of SCOBOL Screens of Netbatch Plus were made. Requests
sent by Web Clients were parsed by Web Server and sent to the appropriate Netbatch Plus server for processing.
Replies from the Netbatch Plus servers were formatted into HTML Pages and sent to respective Web Client.
Implemented the prototype of this project.
The work done on this project served as basis for Pathway/iTS project (a generic solution for making HP NonStop
Applications - “Web enabled”). Also, the concept was used in the development of Web Versions SCF.
Mar’97 – Oct’97
Quality Assurance
Involved in the Quality Assurance process of HP NonStop system products. Process involves running a library of
testcases against new version of a product. New testcases are added to the library for fixes done to a product.
Worked as QA Developer for Axcel, Binder, Crossref and Xllink utilities of HP NonStop. Participated in G02 testing of
Axcel and Binder.
