Worked on optimizing CI/CD workflows for the android/platform-samples repository, focusing on improving pipeline reliability and artifact management. Upgraded the GitHub Actions upload-artifact action to version 4 within the build.yml workflow, leveraging YAML to configure the new overwrite option. This technical enhancement ensured that artifacts are reliably replaced when duplicates exist, reducing the risk of flaky or redundant entries in the build process. By addressing artifact consistency, the work contributed to more stable and reproducible CI pipelines, supporting downstream build and release processes. The project utilized skills in CI/CD automation and GitHub Actions, emphasizing maintainability and workflow reliability.
