I have worked on KVM module and it's feature enhancements.

I was involved in developing Edge software.

EDGE is the Enhanced grocery environment which can help users/customers who visit malls/departmental stores for choosing the product, their purchase history as well as advertisements for the product are embedded in the shelves, also customers are provided with hand held device or they can use APP on the mobile to login to grocery environment to get the idea of products, inventory, discounts and their purchase history. The environment is splitted into two parts one is the board which is embedded in the shelves, which has NFC, blue tooth , ZigBee and wi-fi connectivity modules, also it has display module which can be used to display advertisement, inventory as well as discounts over the product which gives customer to get an enhanced feel with reduced workforce in the grocery environment and live flashing of prices for the products. The other part is the server part which is used to update and upgrade and check the health of the embedded boards fitted inside the shelves. Intel Sunrise is the project based on vending machine in which we were involved in MDB and DEC protocol development.

I was involved in developing HA solution.

OneGate SSL VPN is the product which used for corporate secure connections. It is used for small corporate to very large corporate networks for secure and limited access to office network. It has lot of modules embedded in it. One of the major module is HA (High availability) which gives persistent connection to the office network with 24/7 availability of VPN services.

I was involved in providing end to end product developement of Qatari DPI chip

Tarari is an ASIC chip. It is a content security processor. It resides on PCI bus. The chip is designed to do content processing. User can write his rules in POSIX/PCRE format or in text format. Rules can be downloaded to ASIC chip using regexcp user application. Rule downloading is done with the help content processing module written in Linux kernel. When a user inputs data through regexcp user app, response is given back in start offset and end offset. Visualization for TARARI Chip:(This project was done by me and delivered to Cisco, initially it started with the POC) The regexcp software on Tarari chip allow only single process to access the Tarari chip resources. This limitation doesnt allow multiple virtual machines to access resources concurrently. In field this limitation only allows one VM with one process running and thus not allowing multi process environment. The POC is intended to distribute RegexAgents across processes so that multiple process can share and access resources on the device.

Device driver verifier is designed to help ESX device drivers developers. It is the layer in the kernel which interacts with driver developed and verifies the driver robustness and errors made by the driver developer. This is done by intercepting kernel api calls and then verifying it. We have done for illegal access usage of calls, error injection, low resource simulation. Partly done for network apis. DDK/VTAF is a test automation framework for testing ESX storage/network /FC drivers. It is designed and developed in Perl.

Double-Take is online data replication, disaster recovery software. Double-Take software has developed their own layered file system name dtfs which is based on nullfs file system. It provides high availability and persistent data storage in a cluster.

RHEV is the virtualization platform of Red hat which provides a data center environment for big Enterprise customers They have modules like VDSM, ovirt-engine, and KVM.
