I'm an Electronics and Communication Engineering student building bare-metal firmware for autonomous and automotive applications.

For an automatic agriculture transplanter, I developed STM32 firmware with PWM motor control, UART interrupt-based plant switching, and an ESP32 web interface to control four stepper motors.

I'm developing CAN-based communication between a front zonal controller and centralized computing unit for software-defined vehicles, using the STM32F407VGT6 bxCAN peripheral. My work includes CAN initialization, bit timing, transmission, reception, operating modes, acceptance filtering, and SPI communication with the MC33978 switch interface.

I've also developed wireless ground-station firmware for coordinated scan-and-spray drones and designed a five-band microstrip patch antenna in ANSYS HFSS. I bring hands-on experience with Embedded C, ARM Cortex-M4 microcontrollers, real-time communication protocols, robotics, and computer vision.
