Worked on the philips-software/amp-hal-st repository to enhance the reliability of integration testing for the Amp HAL ST module. Addressed a critical issue in FlashProxy integration tests by implementing missing MethodDone calls, ensuring asynchronous operations signaled completion correctly. This technical approach reduced flaky test outcomes and minimized false negatives in continuous integration, directly supporting release readiness. Utilized C++ for development and applied integration testing and software testing skills to improve test determinism and traceability. The work focused on strengthening test instrumentation, enabling faster debugging and more robust CI pipelines, and contributed to more reliable and maintainable test coverage for the project.
