Experience (India)
IIT Bombay Mumbai, India
Jan. 19 - Aug. 21 Senior Project Technical Assistant, ERTS Lab, CSE Department
Oversaw software and firmware aspects of a pivotal development board crucial for CS684 at IIT Bombay and eY Robotics Competition, engaged by 364 participants.
Designed an ESP32 OTA application, facilitating Wireless AP setup, file serving, and OTA firmware updates for the embedded ATmega2560 and ESP32 microcontrollers on this developmental board.
Adapted ESP32's bootloader and partition table to ensure effortless OTA/user application transition, dynamically governed by real-time GPIO pin status on this development board.
CSIR - National Institute of Oceanography Panaji, India
Jun. 18 - Jan. 19 Project Assistant II
Played an integral role in the development of firmware for data acquisition systems.
Specifically focused on the TS-7260 platform, utilizing its powerful ARM9 architecture.
Authored Python scripts to streamline the data cleaning process, ensuring the integrity and quality of acquired data.
C, HTTP Server, Bootloader, OTA Update, ESP32, AVR
Led the software and firmware side of the development board, which is currently being used in the CS684 course at IIT Bombay and was used in eY Robotics Competition by 364 participants.
Developed an OTA application for ESP32 to start a Wireless Access Point, host a file server and allow OTA firmware update of the onboard microcontrollers, i.e. ATmega2560 and ESP32.
Modified the bootloader and partition table of ESP32 to enable switching between OTA application and user application in the flash, based on the status of a GPIO pin.
Nubot GPS Tracker Numadic
C, Flash Memory, OTA Update, ESP32
Extended life of W25N01GV 1Gb NAND Flash Memory used in Nubot by 29% by developing a custom logical data structure to push data in O(logN) and retrieve data from it in O(logN) (N = Total number of pages in the flash).
Wrote an OTA server to serve firmware and a client for ESP32 to fetch firmware using just sockets in C.
Developed a GATT Client Android App to debug Nubot v2 wirelessly over BLE.
Wrote firmware for this device which enabled it to host an HTTP server and serve a dynamic HTML page to plot temperature logged in real-time and provide an interface for the user to download logged data over Wi-Fi.
