Over six months, Daniel Zemanov worked extensively on the backstage/backstage repository, focusing on Kubernetes access control, permissions, and secret management. He designed and implemented a granular, resource-based permission model for Kubernetes endpoints, unifying backend and plugin access control using TypeScript and Node.js. Daniel enhanced the frontend with permission-aware UI gating and internationalization, improving accessibility and governance. He also contributed to Backstage scaffolder templates by enabling secure secret rendering in repeated steps, with thorough documentation and testing. In the redhat-developer/rhdh-plugin-export-overlays repository, he improved workspace stability and code ownership management, demonstrating depth in DevOps and collaborative codebase stewardship.

February 2025 – Backstage project (repository: backstage/backstage). Key work focused on Kubernetes permissions and internationalization. Delivered: (1) Kubernetes permissions alerts internationalization with translated UI strings and updated docs for Kubernetes cluster and plugins; (2) Kubernetes permissions handling refinements—non-breaking permission description updates, removal of the BREAKING prefix, and version bumps for Kubernetes-related Backstage plugins. These changes reduce upgrade risk, improve accessibility for multilingual teams, and enhance maintainability of Kubernetes integrations. Technologies demonstrated include localization, UI/UX improvements, plugin versioning, and robust Git-based release practices.

December 2024 highlights for backstage/backstage: Key feature delivered: Unified Kubernetes permission model and access control. This consolidates permission naming and mappings across the Kubernetes backend and services endpoints to standardize access control, align with resource-based permissions, and improve security consistency for the Kubernetes plugin. Major bugs fixed: None reported this month. Overall impact and accomplishments: Strengthened security posture by enforcing a resource-based permission model for the Kubernetes plugin, reducing permission drift and enabling easier governance and audits. Technologies/skills demonstrated: Kubernetes RBAC alignment, permission model design, code refactoring for naming consistency, and cross-team collaboration between backend and plugin components.

Monthly summary for 2024-11 focused on Kubernetes access control improvements in the backstage/backstage repository. Implemented a new base 'resource' permission type for Kubernetes endpoints, applied to backend routes, and shifted the permission check to default-allow (deny only when explicitly blocked). Introduced granular permissions for fine-grained access control: kubernetes.cluster, kubernetes.service, and kubernetes.resource. This work lays the foundation for scalable, auditable access governance and future permission policy evolution.
