Worked on CI/CD improvements and security scanning for the deckhouse/deckhouse and deckhouse/modules-actions repositories, delivering three new features over one month. Focused on optimizing CI runners and security scan workflows using Bash and YAML, switching to self-slim runners and refining gitleaks configurations to improve performance and cost-efficiency. Enhanced antivirus scan reporting by restructuring scan directories and automating cleanup, which improved resource management and reliability. In deckhouse/modules-actions, refactored the gitleaks action and introduced a GitHub CLI installer to streamline pipeline setup. Emphasized maintainability by aligning runner labels and job configurations, resulting in more predictable and maintainable CI/CD pipelines.
