ConnectDER, Philadelphia, PA.

Electrical Engineer January 2016 – September 2017

Worked with small team of engineers to design the Smart ConnectDER embedded electronics package along with designing and coding the embedded firmware for the Smart ConnectDER. Worked on development, testing and integration of various parts of IOT based electric meter collar for solar (PV) connections.

Developed Interfacing the SD card to MSP 430 MC for data logging using SPI protocol in embedded C to perform operations on blocks of data from the SD card sectors. Implemented SD card library for interfacing SD cards with MSP430 microcontroller such as MSP430F6736 and MSP430F6779 using SPI-Serial Peripheral Interface.

Designed algorithm for cycle redundancy check for data validation - CRC checks are done for firmware during OTA update after downloading from cloud servers to ensure data is valid.

Designed GUI application to read and write data over Modbus protocol for accessing registers such as holding registers and Analog registers of String Inverters over TCP/IP.

Implemented bootstrap loader & OTA firmware update capability for MSP430 microcontroller and integrated it with LCD display.

Implemented LCD display functionality using Processor to Processor communication based on UART protocol.

Developed & Implemented Over-The-Air updates for the meter collar by creating boot strap loader and firmware downloader code to perform firmware upgrade or roll-back firmware to units in the field.

Developed hardware PCB and firmware for test-bench to perform hardware check during manufacturing and assembly process for the unit’s motherboards.

Performed ANSI, UL tests on the 3-phase and 2-phase energy meter collars with documentation.

Performed Calibration of voltage, current, power on the meters to maintain the readings within the specified range meters using RFL-5800 application.

Maintained and performed GIT based source control and tagging over the past 2 years for all firmware and hardware design works.

Worked on establishing server client communication mode using AT Commands on a 4G LTE network, by issuing HTTP GET / POST requests to remote server.

Skill Level: Intermediate

Two years of experience with Simulink.

Two years of experience with Altium for PCB design. Skill Level: Novice

One year experience with C++, Assembly for

processors, and Drupal CMS, PLC programming.

Performed Firmware QA tests for smart IOT embedded systems by using various test cases to test the Data Integrity, Power outages, Relay control, Network errors and HTTP errors.

Performed Firmware QA tests on smart IOT collar using Modbus protocol in private VPN to make API calls using POSTMAN application. The aim was to test the various test cases of HTTP POST, GET queries for readings such as Power Factor, Power, Voltage, Current, Active Power etc. Wipro Technologies, Hyderabad, India
