During April 2025, Duygu Ooz worked on the common-voice/common-voice repository, focusing on enhancing Docker image build security and CI/CD hygiene. She implemented a .dockerignore file within the Docker directory to ensure that sensitive and generated credentials, such as those from google-github-actions/auth, were excluded from the Docker build context. This approach reduced the risk of credential leakage and improved build isolation, aligning the workflow with established security best practices. Duygu utilized Docker and Dockerfile expertise to address these concerns, demonstrating a methodical approach to container security. No major bugs were fixed during this period, reflecting a targeted feature effort.
