During December 2024, this developer enhanced the CI/CD workflow for the datalens-tech/datalens-us repository by upgrading artifact management in YAML-based GitHub Actions pipelines. They implemented an overwrite feature by moving actions/upload-artifact from version 3 to 4 in both publish_platform.yaml and publish_platform_hotfix.yaml, ensuring that subsequent uploads with the same artifact name would replace existing files. This change eliminated duplicate artifacts and reduced confusion in storage, resulting in more deterministic and maintainable release processes. Their work demonstrated proficiency in CI/CD automation, GitHub Actions, and YAML configuration, with a focus on improving artifact traceability and operational efficiency within the repository.
