Michal Kozak engineered deployment and infrastructure enhancements across the keboola/keboola-as-code and keboola/mcp-server repositories, focusing on automation, security, and observability. He modernized CI/CD pipelines using GitHub Actions and Terraform, integrated Helm for streamlined deployments, and improved traceability by linking image tags to pipeline commits. Michal strengthened image sourcing security by configuring etcd Helm charts to use internal registries with pull secrets for AWS and Azure environments. He also enhanced observability by adding distributed tracing with ddtrace and consolidated registry management to reduce operational complexity. His work, primarily in Python, YAML, and Bash, demonstrated depth in DevOps and cloud-native engineering.

Month: 2025-08. Focused on securing and stabilizing etcd image sourcing for Keboola deployments by enabling custom registries and pull secrets across AWS and Azure. Updated the etcd Helm chart to use internal registries, with private registry pull secrets, improving control, governance, and security of image sourcing in Keboola environments.

January 2025: Delivered a CI/CD traceability enhancement for keboola-as-code with Argo deployments. Implemented a GitHub Actions workflow enhancement to accept a commit-sha input and write the pipeline SHA to tag.yaml alongside the image tag, enabling precise traceability of deployed images to the specific pipeline commit that generated them. No major bugs fixed this month. These changes improve deployment governance, incident response, debugging efficiency, and auditability across environments. Technologies used include GitHub Actions, YAML, and Argo CD workflow integration.

December 2024 monthly summary for keboola/keboola-as-code: Focused on stabilizing token generation, improving release automation, and reducing maintenance overhead. Key features delivered include standardizing CSRF token salt generation by replacing the 'xxd' utility with 'hexdump' to ensure consistent hexadecimal output while preserving functionality. Release automation improvements include adding GitHub Actions workflow triggers to automate kbc-stacks image tag updates, removing outdated GCP provisioning scripts, and introducing a local action to trigger image tag updates, refining the release workflow and developer experience. Technical impact encompasses enhanced reliability of CSRF protection, faster and more predictable image tag updates across repositories, and a leaner, more developer-friendly release process.
