1. Embedded firmware development in C on 32-bit ARM Cortex-M class microcontrollers.
2. Wireless: Bluetooth Low Energy — scanning, advertising, connection management, and custom manufacturer-data packet design. Familiarity with cellular (LTE Cat-1/Cat-M) AT-command or modem-driver integration and GNSS (NMEA/NavIC) parsing.
3. RTOS & SDK: Zephyr RTOS and Nordic nRF Connect SDK (or comparable — FreeRTOS, ARM CMSIS). Comfort with devicetree, Kconfig, and the pinctrl/board-porting workflow.
4. Peripheral & bus work: SPI, I²C, UART, ADC, GPIO/interrupt handling — including wake-capable interrupt configuration for event/crash detection.
