Experience

At Yahoo:

• Starling: A tool to populate a data-warehouse by processing different types of logs collected from various Apache Hadoop clusters in order to analyze utilization, performance and usage of these clusters. The data are collected and processed using Oozie work-flows, stored via Apache HCatalog on Apache Hadoop HDFS and analyzed using Apache Hive and Apache Pig. Principal designer and implementor.
• GridSim: A collection of tools for evaluating the performance of Apache Hadoop clusters, including GridMix3, a MapReduce load-simulator and stress-tester that uses traces obtained from production-clusters to emulate various types of loads, and PigMix2, a load-simulator and stress-tester for Apache Pig. Team member.

At Oracle:

• Oracle Enterprise Manager: A product used to manage and monitor systems deployed in an organisation. Member of the team that maintains the patching feature. Security Point of Contact (SPoC) for the team.
• Oracle Software Packager and Universal Installer: The tool-set used to create installers for Oracle's server products. Team member.

At Headstrong:

• TradePort: An order-management system for brokerage firms and trading houses that supports multiple order destinations and has a comprehensive risk-management system. Principal designer of the Common Service Framework for TradePort Server services.

At Torry Harris:

• dotFlow: A distributed work-flow engine for Java that also provided a studio to design work-flows. Principal designer and implementor.
• ASPizer: A framework that provided an infrastructure over a J2EE-based application server that let Application Service Providers (ASPs) manage their users, security, licensing, billing, etc. Completely distributed environment with remote administration capabilities and a handy web-based administration application. Principal architect and designer.
• WebOBlocks: A framework that provided a component-based methodology for rapidly building web-applications to be hosted on J2EE-based application servers. Based on the Model-View-Controller (MVC) architectural pattern. Principal designer and implementor.
• Others: EazyCache - an object cache for Java, WLM - a Work-load Management tool for Distributed CICS, Java/IIOP for Distributed CICS, etc.

At IBM:

• Consumer Transaction Framework: Designed and built some extensions (a personal finance management framework, a TN3270 emulator and a WhiteBoard) for the IBM Consumer Transaction Framework (CTF). Principal designer and implementor.
• alphaBeans: Designed and developed some JavaBeans that ultimately became a part of IBM alphaBeans.
• AIX Server Support: Provided “Level-3” (L3) support for the command-line programs available to AIX users.

Papers and Presentations

• “Hadoop Simulation and Performance” at the Apache Hadoop India Summit 2011.

Personal Projects

• GCJ: I was a contributer to the GNU Compiler for Java (GCJ) and the GNU Compiler Collection (GCC). Among other things, I helped create a Windows-native port of GCJ using MinGW (based on the work of Adam Megacz) and fixed several bugs in the Java front-end of GCC.
• GDB: I helped create a Windows-native port of the GNU Debugger (GDB) version 5.2.1 using MinGW (based on the work of Artem Khodush).
• ZINC: A simulator-cum-assembler for playing a variant of Core War, a game where programs fight each other inside a virtual machine.
• VirtualTaj: An interactive 3D walkthrough of the famous Taj Mahal that runs on Windows and Linux and was developed using OpenGL and SDL.
• The Hobbitware.com Intranet Project: A guide to setting up a complete intranet for a small organization using free server software on Linux, based on personal experience.
• Disasm: An intelligent disassembler for x86 that produced valid assembly-language programs from MS-DOS executables.
• Fox3D: A simple ray-casting 3D engine for walking through a maze, somewhat similar to the game Wolfenstein 3D by id Software.
• PMars: A simple voxel landscape engine inspired by the “Mars” demo by T. J. Clarke, written almost entirely in x86 assembly-language and using the x86 Protected Mode under MS-DOS.
• Core War: Another assembler and simulator created earlier for working with Core War programs as described by A. K. Dewdney.
• Others: An assembler/simulator for Knuth's MIX, a fast Mandelbrot set explorer, etc.
