• Part of Prototype team, which creates the JBOF for PCIe SSDs and share between different Hosts. Capable of delivering 9M IOPs.
• Development of PCIe Driver for NTB and NVMe driver. This Project enables Storage SAN of PCI based NVMe.
• Purpose Design changes in current code to support dynamic flusher.
• Development of caching based solution for ESX 6.0 using IO Filter API’s provided by VMWARE.
• Implementation of Snapshot handling.
• Virtual Desktop Infrastructure (VDI) Implementation for Caching Software. It includes differentiate between RO data and RW data. OS Image same for all VM’s and caching that increase the throughput of each VM.

• Worked on mmc pre and post request functions in Samsung’s eMMC HCD. These functions minimize the latency to start and end an mmc request. The cache maintenance operations are done while an mmc request is active.
• Implementation of Read Request Split into two sub request at MMC subsystem.
• Worked on Ext4 Utility which convert any raw data into ext4 image.
• Debugged 3rd party eMMC HCD for Async IO support and performance issues.
• Worked on mmc abort request function in Samsung’s eMMC HCD for HPI feature support. eMMC HPI feature is used to interrupt an ongoing mmc write request so that high priority requests like demand paging requests can be serviced.
• Worked on feasibility of eMMC 4.5 features like BKOPS, PON, Cache, and Packed Command. BKOPS (Background Operations), PON (Power off Notification) are used to increase the endurance of eMMC. Cache and Packed Command to increase the throughput.

• Worked on Mobile Devices in different areas.
• Linux Kernel Porting to different board which requires changes to Bootloader, kernel.
• Worked on WiMAX Application which interacts with the WiMAX driver through Java Native Interface (JNI).Application passes the event to interface layer which call HIM function which passes the desired control messages to driver. This project requires to changes in framework and interface layer.
• XT9 Engine Porting on Qualcomm given Text controller. It involves the writing of OEM Text Controller (As BREW Mobile Platform can’t be changed). It involves writing of new layer from scratch as BMP don’t allow to change the code. Integration with other applications like Browser, social networking sites, Email etc.
• Implementation of WIFI application which interacts with the driver, Application call interface API to communicate with the driver. Interface passes the information to driver for through connectivity manager. Connectivity Manager Pass control message to desired driver.
• This project involves development of GUI using BREW for Image Editor Application. Integration with gallery application.

• Studied the MMS Viewer of Obigo solution as acquired by our company. To enhance the MMS viewer on part of memory usage like RW, RO. Apart from the memory usage working on support of MMS 1.3 on it.
• Enhancement on the store module which stores the mms differs from previous model as keeping the table about all the folders and detail about them.
• Worked on the Error check implementation on the MMS file. The File which are corrupted should be left at it is. It helps me understanding the storage of MMS, Retrieval of Messages, and Various scenario on boot up of Mobile. It also help me to know header information present in MMS during composing, receiving, sending.
• Implement new feature which enables our mms to handle fit tag which comes with smil .Fit Tag determine the placement of media and its region. It also describe the presentation of media according to different fit tags.
