Prototype a communication between arduino ( Uno ) with Bluetooth LE module to Bluetooth LE mobile app to receive sensor information.

Nov 2016 – July 2017

software engineer

Contract (onsite Comcast-Wipro)

language / frameworks : C++, python, linux

Implemented following features for Comcast Smart home solution.

RDK-C platform for camera middleware. Involved in webpa, and camera video analytics engine comparison and supporting json information as part of home automation project.

commissioning camera on the cloud server, it was in java ( spring framework ), introducing new states in setting up / provisioning the camera.( worked on for around 2 months).

Implemented tr181 support for Camera middleware.

Implemented additional features for RDK-B support/feature for speedtest and xsmart client( IOT) . Used quilt, devshell, yocto build .

Senior Staff Engineer

Echostar

Atlanta, USA

language / frameworks : C++, python, shell script, linux

Member of SAGE home automation product team. Worked with Mstar (chip vendor) for our SAGE home automation SW requirements. It was in C/C++ on embedded linux. My responsibilities were

Implemented SAGE HAL specification.

Implemented test suite for initial vendor code acceptance/verification .

Functional testing on zigbee, z-wave for SAGE boards ( for first revision boards). We interfaced with vendor supplied test suite on linux platform.

Involved with boot-loader (for support for various flash types), linux kernel raw-NAND/mmc device support, flash memory partitioning and allocation for SAGE functionality.

Implemented and debugging communication between SAGE and cloud server (for communicating to mobile apps) forming JSON, REST queries. We used rabitmq messaging.

language / frameworks : C, vxworks, linux 3.1

Member of XLP ( multicore, multi-threaded MIPS SOC ) software team . Implemented device driver software for hardware features on XLP on Vxworks and Linux. It was in C. My responsibility were

Implemented XLP processor as a PC with support for peripherals. XLP processors with embedded linux as OS perform switching/routing operations. The requirement was to have XLP processor used as a PC .

kgdb over ethernet implementation in embedded linux. Kgdb over console is the standard implementation . This was on montavista linux for which kgdboe was implemented.

Network driver support for montavista ( embedded) linux.

Implemented security api for crypto driver in vxworks 5.5 .

Implemented pcie support for vxworks for XLP processors.

Flattened device tree implementation in vxworks5.5.

Central messaging Station ( XLP proprietary hardware feature ) software implementation to support the hardware feature which enables processor to processor and processor to IO peripheral station ( vice-versa) communication.

Serial Rapid IO driver support for vxworks5.5 .

Network driver MDIO bit interrupt handling.

Used ejtag, kgdb tools .

May 2004 – Dec 2008
