Firmware Developer May 2019–August 2019

Developed firmware for a cloud-connected IoT device using Micropython on Digi Xbee3 NB-IoT module. The device is capable of sending sensor data from remote locations to a server intermittently. Implemented OTA updates of the firmware and the configurations thatdoes not require any kind of physical interaction. It has an expected battery lifetime of 5-7years using two 3.7V AA size battery. Helped in designing and debugging the Daughterboard which contains all the auxiliary circuitry necessary for sensor interfaces and controls of the whole the unit. Implemented basic server side code in python to test the whole system. This product will soon be available commercially across the US and hopefully the world.

Graduate Research Assistant August 2016–Present

1. Research work on Security in Bluetooth Low Energy, resulting in discovery of major flaws in BLE security in both Android and iOS system. Android Security team has rated this finding as having "High Severity" Paper arXiv Link 2. Research work on system on chip microcontrollers (ESP32, ESP8266 etc) used for various Internet of Things(IoT) application, resulting in a research paper on bench-marking their efficiency. Paper IEEE Link 3. Designed printed circuit board (PCB) using EasyEDA and 3D printed cover using Autodesk to commercialize a secure PM2.5 Sensor as a part of a NSF Cyber Physical Systems grant 4. Research work on Software Defined Radio (SDR) using a modified TV Tuner, resulting in a Secure Spectrum Sensor using MQTT Protocol. Which sends RSSI values of a radio frequency in a particular location to a server live, along with the coordinates of that location. This radio frequency range can be controlled live from the server/controller side via secure TCP connection. For security, certificate based TLS communication for MQTT have been implemented. Language: Python Code

Graduate Teaching Assistant August 2016–Present

1. Created and graded assignments/quizzes of 65+ students and helped them understand the content better for the course Embedded Systems (EEL 4742), Engineering Analysis and Computation (EGN 3211) and Digital Systems (EEE 3342). 2. Taught two sections of Electronics 1 Lab (EEE 3307) with n=35, Intro to C (COP 3223) with n=15, Systems Software (COP 3402) with n=175 resulting in almost 100% of the students getting an A. Relevant Projects

+ Regularly practice my coding skills on websites like Hackerrank.com. My codes are available on my Github.
