IBM Blue Cloud Computing
Developing automation technologies which will enable computing across a distributed, globally accessible fabric of resources. Automated provisioning, configuration and installation of AIX virtual machines for the IBM Cloud computing project.

Design and Development of a Backup and Recovery Appliance for System P Servers of IBM.
Main design goal was to provide a light weight backup and recovery solution for SME/SMB customers of IBM who use AIX. Users can perform backup and restore operations of volume group, logical volume, filesystem and file in any partition connected to the appliance. Full system(mksysb) backup and restoration of full system using Network Installation Manager(NIM) is also supported. All the operations can be done on Web UI which is built on the Integrated Solutions Console (ISC) and Light Weight Infrastructure (LWI) framework of IBM.

Integrated WPAR Management (IWPAR)
An IWPAR is a pre-installed, pre-packaged, pre-configured and pre-tested WPAR which contains an optimized Operating System and a set of software focusing towards achieving single business goal (for example, web serving). It also includes Manageability services for managing the software and enable high degree of customization. Once IWPAR is deployed, it runs as a normal WPAR. Workload partitions (WPARs) provide a software solution for creating virtualized operating-system environments for managing multiple workloads.

Balanced Configuration Unit (BCU) Toolkit
The E7100 Balanced Warehouse is a combination of hardware and software carefully constructed to provide an optimal environment for database applications. Hardware comprises of System P servers with AIX as the OS. Deployment of a Balanced Warehouse environment can be a time consuming process. BCU Tool Kit was developed to automate AIX OS installation, Software installation and initial AIX configuration processes with a minimal amount of manual interaction.

AIX Basic Operating System Commands
Debugged few critical AIX basic operating system commands like ls, vi, pg, make, libcurses, od, csh etc..,

L2C: Learning to Collaborate - European Union Funded Project
The aim of project to develop the framework (tools, techniques and guidelines) for distributed collaborative games. We have identified common characteristics and requirements of the distributed collaborative simulation and come up with framework for the same. The proposed framework contains Messaging system for transferring events to all collaborating users, persistent notion of state of the game on a centralized server and protocol for messages transferred between users. Few prototype games ("World Music Game", "Globank", "World Tech Strategic IT Initiatives", "Fire Them All" and "Simple Network Editor") have been developed on top of this framework. Tools have been developed to simplify the process of creating new multiplayer games and to manage theses games effectively.

Intelligent Agents:
This involves integration of Intelligent Agents ("Living Actors") into the computer based simulations (serious games). These agents can interact with the users in real time. Worked closely with Austrian Research Institute for Artificial Intelligence (OFAI) and created an API for these simulations. OFAI use this API to control the subsequent actions of the agent based on users responses.

Word2Fo
Developed the tool Word2Fo which helps in creating XSL Stylesheets and PDF files from Word documents which are primarily insurance certificates. First a WordprocessingML document is created from a word doc which has design template and data mapped to an XML file. Then it is converted to a XSL-FO document using XSLT by mapping each tag in WordprocessingML schema to corresponding XSL schema. A FOP engine is used to render the XSL-FO document into a variety of output formats, including PDF, text, MIF, Postscript, and others. An add-on for Microsoft word is created to perform all these tasks. It was developed using XSLT, XPath, XSL-Fo, XML, VBA and Java.
