Worked on enhancing the testing framework for the sgstorage module within the google/oss-rebuild repository, focusing on improving the reliability and coverage of system graph loader tests. Developed utilities in Go to generate test data, automate directory creation, and zip files, streamlining the setup of complex test scenarios. Leveraged protobuf to convert text proto blobs into binary proto blobs, enabling more thorough validation of the loader’s behavior. These improvements stabilized previously flaky tests and contributed to more robust continuous integration workflows. The work demonstrated a strong command of Go, protobuf, and testing methodologies, with an emphasis on engineering for test reliability.
