Confidential

Design and developments of settopbox stack

• Client interaction for requirement gathering.
• Worked in developing of GUI and API’s of Settopbox for the interaction with the hardware.
• Development of Platform abstraction layer for proprietary middleware and GUI using Nexus API’s.
• Develop the code in C, C++ having Linux as platform, used cross compiler toolchain for MIPS Architecture.
