Worked on the oss-slu/Pi4Micronaut repository to enhance both test reliability and documentation clarity for hardware integration. Addressed a persistent issue in Java unit tests by correcting the MicroSwitchHelper test file naming and ensuring tests targeted the correct helper instance, which reduced CI flakiness. Simultaneously, reorganized hardware component documentation written in adoc, introducing clearer section groupings and adding new entries such as the Reed Switch. These improvements streamlined onboarding and knowledge transfer for future contributors. The work demonstrated a methodical approach to maintainability, leveraging skills in Java, documentation, and unit testing to support smoother development and review processes.
