Physics student at SUST with a passion for embedded systems. Research Assistant at the EEE Department working on autonomous navigation and IoT solutions. I build device drivers and maintain the Biometrics subsystem for Zephyr RTOS (Linux Foundation), supporting developers across ARM, RISC-V, and Xtensa platforms.
