Experience:

Currently Working as an Embedded engineer in Continental Automotive Singapore pte ltd, Singapore.

Worked as an Embedded engineer in Soctronics Technologies PVT LTD, Hyderabad, India.

Worked as an intern in Soctronics Technologies PVT LTD [VEDA IIT], Hyderabad, India.

Qualification:

Master of technology in Embedded systems from Vignan’s university, Guntur, A.P., India.

Bachelor of technology[ECE] from JNTU Kakinada, A.P., India.

Projects:

1. Audio driver and firmware development for Moto Mods of Android Motorola z plus mobile:

Project Name

Moto Mod

Role

Developing audio Codec Driver and developer testing

Platform

For codec driver: Windows, keil

For firmware: Linux

processor: ARM Cortex-M3

Audio codec: cirrus logic

Description:

Mod is external pad which will fix at back side of Moto Z plus phone. This is to support high quality audio play back, camera and projector. These mods consists of STM32 MCU and these will communicate with moto phone through grey bus protocol.

My contribution:

Implemented some features in audio codec driver and in firmware and written unit tests for driver code testing then verified code quality using Cppchecker.

2. Audio driver and firmware for Bluetooth headset:

Project Name

SBC encoder and decoder

Role

Application and Codec Driver Developement

Platform

Windows, keil, Free RTOS

processor: ARM Cortex-M3

Audio codec: Cirrus logic[Moon]

Description:

This is a firmware for managing encoding of audio data from MIC into .sbc format and storing to SD card then decoding sbc file by reading from SD card and playing back to speaker. The final product is blue tooth speaker which will do playback of these sbc files and encrypts audios captured to sbc format.

My contribution:

Implemented total firmware for buffer management and audio codec driver.

3. Amazon Alexa:

Project Name

Console app and sensory

Role

Development and testing

Platform

Platform: Linux, Raspberry pi3

Description:

Amazon Alexa is an voice assistant like Google. We developed an c++ app which will take commands from codec MIC and sends to Alexa cloud. Again takes response from cloud and plays to codec speaker.

My contribution:

Done performance testing, functionality testing and integrated sensory algorithm to application.

4. DSP Firmware IOT MAC for Itron wireless smart meter:

Project Name

Smart electric wireless billing meter

Role

Developer and Testing of DSP MAC firmware

Platform

Windows, Xtensa, Threadx RTOS

Hardware: NIC

processor: ARM7 and Tensilica LX6.

Description:

This is related to IOT. Every house consists of a wireless Smart billing meter which acts as a node, we can connect with these nodes from main station with the help of root for generating electric bill with out visiting every house. These consists of multiple Personal area networks[PAN]. Each PAN consists of one root and multiple nodes. A city can be covered with multiple PANs which will connect to each other through their roots. In network stack, we used IEEE 802.15.4 standard and it consists of Application layer, Network layer, Data link layer, Physical layer. We implemented Data link layer[MAC layer] for wireless communication.

My contribution:

Implemented some features in DSP firmware and test cases for mac layer protocols, done system testing, functionality testing and network testing[end to end testing].

5. Linux Audio application development for Automotive telematics project on Qualcomm Soc chipset:

Project Name

Automotive Telematics ecall

Role

Developer

Platform

Linux, Windows, Xtensa,

Hardware: Continental specific

processor: ARM7, Qualcomm SOC and TI Audio codec.

Description:

This is related to Automotive telematics emergency call used in cars in case of emergency situations. It contains multiple modules. I worked in Audio module application. This is to play audio and voice in emergency call. This is the main module in entire project as the working functionality of the project can be identified by audio prompts and voice.

My contribution:

Implemented some audio application features in Linux. Analyzed audio logs in case of client issues and provided fix. Discussed with Platform teams for Audio Linux driver and HAL code support. Support given in client testing and in production.
