Developed Zephyr RTOS firmware and drivers for BMA400, LIS2DW12, and MC3635 MEMS accelerometers, covering I2C/SPI communication, register configuration, interrupt handling, and power-mode management. Built low-power, interrupt-driven sensing applications on ESP32 and Nordic (nRF Connect SDK) platforms, turning raw accelerometer data and interrupts into product-specific events without continuous polling. Validated accelerometer performance across ODRs and power states, and profiled current consumption with the Nordic PPK2 to optimize battery life.
