Worked on the deckhouse/modules-gitlab-ci and deckhouse/modules-actions repositories, focusing on CI/CD automation and DevOps reliability. Addressed SSH key handling in GitLab CI by ensuring setup scripts executed only with valid keys and improved SSH agent termination to prevent lingering processes, reducing CI failures related to authentication. Enhanced Svace integration by introducing a configuration-driven function for import parameters, adding error handling, and refactoring project and branch management for greater flexibility. Improved CI configuration safety by clarifying variable usage in Svace Analyze jobs. Utilized Shell scripting, YAML, and GitLab CI to deliver targeted fixes and workflow enhancements over two months.
