PROFILE
Jerry Jia
Jerry Jia developed and refined the ADC driver and estimator modules for the waterloo-rocketry/cansw_processor_canards repository, focusing on robust analog data acquisition and real-time state estimation. He implemented a HAL-based ADC interface in C, enabling continuous sampling through FreeRTOS tasks and integrating interrupt-driven data capture for low-latency sensor readings. Jerry improved code maintainability by standardizing headers, removing deprecated APIs, and enhancing thread safety. He also established groundwork for sensor fusion and Kalman filter-based state estimation, structuring IMU data pipelines to support future EKF integration. His work demonstrated depth in embedded systems, driver development, and real-time operating systems integration.
