Worked on the NVIDIA/dbus-sensors repository to enhance sensor lifecycle management during host power cycles, focusing on stability and error resilience. Addressed a core-dump issue by ensuring sensors were only created in the PowerOn state, using C++ for robust system programming and embedded systems debugging. Implemented logic to deactivate sensors on host power-off and reliably recreate them on power-on, improving I2C sensor handling for devices like CX7 and BF3. Added comprehensive error handling to prevent daemon crashes and resolved a race condition that caused duplicate device initializations, directly fixing nvbug 5165270 and validating system stability during rapid power transitions.
