Developed and integrated an RTM Controller Configuration Enhancement within the facebook/fboss repository, focusing on decoupling the RTM controller from MDIO and introducing an independent RTM_CTRL configuration flow. This work involved updating platform management logic and device lifecycle handling to align with the latest retimer driver, resulting in improved hardware onboarding and reduced integration risk. Leveraged C++ and Python for platform logic, device driver development, and embedded systems integration, while updating configuration files and sysfs mappings to support new device paths. Ensured code quality through adherence to linting and pre-commit checks, validating end-to-end device creation and system stability throughout the process.
