PROFILE
Steve Keay
Steve Keay engineered robust network automation and infrastructure synchronization features for the rackerlabs/understack repository, focusing on seamless integration between OpenStack, Nautobot, and Argo-based workflows. He delivered event-driven synchronization to decouple Nautobot updates from OpenStack Neutron, improving reliability and reducing operational risk. Using Python and YAML, Steve implemented modular, site-specific configurations and enhanced error handling, type safety, and observability throughout the stack. His work included backend development, API integration, and infrastructure as code, addressing complex multi-domain and multi-tenant scenarios. The solutions demonstrated depth in automation, maintainability, and security, resulting in more resilient, scalable, and auditable cloud network operations.

Sep 1, 2025September 2025 monthly summary for rackerlabs/understack: Focused on stabilizing Nautobot integration with OpenStack Neutron by decoupling the Nautobot updates from the ML2 mechanism driver and introducing an event-driven synchronization workflow. This reduces operational risk when Nautobot is unavailable and ensures Neutron networks/subnets stay in sync with Nautobot across CRUD events. Major changes include create/update/delete event handlers and Argo Events sensor configurations, laying the groundwork for scalable automation and future integrations.

Jun 1, 2025June 2025 monthly summary for rackerlabs/understack. Delivered a security-minded Keystone synchronization feature that conditionally creates the OUTSIDE network only for projects in the default domain, preventing unintended external network provisioning for special-purpose projects. This change strengthens security posture, reduces unused resource allocation, and improves governance and auditability. The work is documented by the commit: eddc553ce19f459351080d805521fa5887f16f7d.

May 1, 2025May 2025 monthly summary for rackerlabs/understack. Focused on expanding cross-domain Nautobot synchronization with OpenStack and improving code quality. Highlights include: (1) Cross-domain Nautobot synchronization enabling complete visibility of all OpenStack projects by removing domain restrictions and implementing domain-prefixed tenant names; (2) Code formatting cleanup (Ruff) across Python files to improve readability; (3) Simplified synchronization flow by removing the --only-domain argument and related validation logic. These changes together drive better operational insight, reduced cross-domain conflicts, and maintainable code.
