- Developed a data logger using ESP-IDF, which logs data from meters periodically over RS485 using the Modbus protocol, and then sends the data over the internet using Wi-Fi and HTTPS API calls, all from scratch. - Developing offline logger software for Windows OS using python, react, CSS, html, MySQL. It logs data from meters periodically over RS485 using the Modbus protocol and stores it in the MySQL database. Records can be generated in pdf format with a selectable interval and date range. It also has WebUI for live viewing that shows a graph. Mostly from scratch, my part was with backend (python and SQL). - Board bring-up for MS51 MCU and ESP32. - Worked on communication protocols - SPI, UART, Modbus, I2C, MQTT, Rest API. - Worked on Peripherals - ADC, Interrupts, GPIOs, Watchdog, UART, Timers, - Improved software development workflow and structure by having a common folder for libraries like Modbus, LCD, etc. with different .h and .c pair with mostly architecture independent and modular code (somewhat like STM32 CubeMX). - Developed GUI for easy meter calibration. Made using python and Tkinter Implementing new APIs and libraries. Modifying existing firmware and adding new features for meters. Porting existing code from Microchip PIC16 to Nuvoton MS51. Working on wired communications protocols that include RS485, RS232, and Modbus. PCB and circuit design.

- Supported the development and implementation of new features, updates, and troubleshooting solutions for Zigbee protocol (ZStack) on the CC2530 microcontroller. - Contributed to the development and maintenance of a BACnet Controller software application that functions as a BACnet Client to control BACnet devices. This includes assisting with bug fixes and feature enhancements. - Worked on a Meshnet Controller software application that bridges ZigBee communication with Linux for control of ZigBee devices. - Utilized Embedded Linux and Raspberry Pi for the development of the BACnet Controller software

Hired as in hardware intern. My day-to-day task is to test firmware, develop firmware, and document development boards that are developed in-house. All these are on ESP8266-12F/E/N MCUs.

We made a prototype of a pill management system, in this, there is an app and IoT device. As most old age people cant operate smartphones so caretakers of an old person can set up reminders on a smartphone to take pills which will be displayed on the IoT device
