Worked on the 2gis/on-premise-helm-charts repository, delivering two key features over two months focused on Helm chart management and DevOps automation. Upgraded the Pro-API Helm chart to version 2.26.0, introducing audit logging, configurable worker threads, and improved authentication, while refactoring environment-specific settings for greater consistency. In a separate effort, implemented a comprehensive CI/CD pipeline using Bash, GitHub Actions, and Docker, automating Helm chart linting, documentation, and release notifications. Standardized repository governance with pull request templates and compliance files, streamlining collaboration and release readiness. All work was delivered in Markdown and YAML, emphasizing maintainability, security, and operational transparency across deployments.
