PROFILE
Jonathan Haab
Jonathan Haab contributed to the CHORUS-TRE/chorus-tre repository by engineering robust deployment and CI/CD workflows over five months. He implemented features such as GitOps-driven configuration, MariaDB initialization via Kubernetes ConfigMaps and Secrets, and persistent storage for build artifacts using Helm and Kubernetes primitives. His work included refactoring resource naming, automating workflow cleanup with TTL controls, and enhancing release packaging through versioned Helm charts. Using Go, Python, and YAML, Jonathan focused on maintainability, security, and deployment reproducibility, addressing operational risks and streamlining upgrades. His solutions demonstrated depth in DevOps, configuration management, and container orchestration, resulting in scalable, reliable infrastructure.

46 Commits • 11 Features
Oct 1, 2025October 2025 performance summary for CHORUS-TRE/chorus-tre focused on stabilizing storage, improving resource naming consistency, and elevating CI/CD reliability to drive business value in build orchestration and resource usage. Key accomplishments include: - PV-based volume management for backend, webui, and workbench builds, with a generate-volume step and storage defaults to simplify capacity planning and reduce manual intervention. - Unique PVC naming with an ID suffix and path/script refactor to prevent collisions across concurrent builds and resources. - TTL-based cleanup of successful workflows (default 5 minutes) with configurable TTL via values, and standardized docker-data naming to improve resource lifecycle management. - RBAC/resource provisioning: added PVC resource to the Chorus CI role to enable PVC operations safely within CI workflows. - CI and release readiness: upgraded Chorus CI tooling, refactored image registry handling to remove hardcoded values and support template-based image selection, and introduced a wrapper step around generate-volume and docker build to streamline orchestration. Overall impact: improved resource utilization and cost control, enhanced reliability and scalability of build workflows, and a cleaner, more maintainable deployment configuration. Demonstrated proficiency in Kubernetes storage primitives, RBAC, Helm-chart-driven releases, CI tooling, and scripting improvements.
