• Middleware designing and development to port Android on Linux based O.S. tizen (Our team developed a middle ware between Android Application and a Linux based Operating system Tizen, to facilitate Android Application on Tizen. We ported Android FW (framework) and Android HAL (Hardware abstraction layer) over Tizen.)
• Designed and developed Android boot process on Tizen(Linux based) operating system.
• Have good understanding of Binder Inter process communication.
• Tizen O.S supports eglibc,While Android support bionic libc. Our team designed and developed customaries DVM (Dalvik virtual machine), Linker and loader for Android native Application (NDK) support on Tizen O.S.
• Designed and developed Android framework and Android hardware abstraction layer to port Android Wi-Fi, GPS, and on tizen operating system.

• 1. Participated in the development of DLNA stack, my core responsibility was debugging and the issues in the stack. 
• 2. Developed search capabilities and SSDP update (updating on DMC (controller) side when any update on the DMS (server) side), in the DLNA stack.
• 3. Developed DMP (Digital Media Player), which is similar to DMC but it has its own player for playing of multimedia data.

• Long Term Evolution: Messaging Frameworks, Memory Manager Handling ,UE
• I worked for memory manager, Messaging framework, DCT(data collection tool of UEs),
• 1. Memory Manager static library: In a Real Time System to avoid the run time memory allocation/de-allocation, private buffers are created for processes/threads. This library provides the interface to achieve that.
• 2. Messaging Framework library: It was POSIX message queue based IPC library toprovide interface for processes/threads to exchange messages.
• 3. Enhanced the “timer library:”: which provides the interface to the processes/threads to start guard timers.
• 4. DCT (Data Collection Tool) SW: This SW refers to a tool for directly collecting, displaying and storing information, such as measurement items and the internal state of the equipment. This is enabled by directly connecting the client terminal (DCT-PC) to the eNodeB base station equipment.
• 5. Implemented the Serializer/De-serializer for certain SOAP-XML messages. The Serializer function converts the C message to XML message and De-serializer does the reverse conversion.
• 6. Implemented some UE control APIs, providing the function to fetch the “number of active users (UE) per cell” and for the “number of users undergoing handover procedures and related source/target cell information”.
• 7. Worked on the X2AP Protocol that is Protocol to create interfaces between Two eNodeBs.
• Duration: Sep 6,2010 - Dec 2010
• Multi Party Conference Chat Server
• 1. The project was aimed to chat among multiple clients through single server in multiple sessions. Socket programming used in this project.
