PROFILE
Steve Keay
Worked extensively on the rackerlabs/understack repository, delivering robust automation for baremetal provisioning, network lifecycle management, and infrastructure synchronization across OpenStack and Nautobot. Leveraged Python and YAML to design event-driven workflows, enhance API integration, and implement modular, site-specific configurations using Argo Workflows and Kubernetes. Focused on reliability and maintainability, the work included centralizing enrollment logic, optimizing boot and inspection sequences, and improving error handling and observability. Introduced secure firmware delivery via CDN and Nginx, strengthened type safety, and streamlined cross-domain synchronization. The engineering approach emphasized scalable automation, strong typing, and operational clarity, resulting in resilient, maintainable backend systems.

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.

Nautobot API integration improvements (9 commits) added VNI association for external subnets, switched updates to PATCH, and included robust error handling and rich logging/diagnostics. External network lifecycle and understack SVI support in Neutron (8 commits) introduced automatic OUTSIDE networks per project with RBAC-managed external access and SVI controls, plus enhanced logging and type handling. Major bug fix: corrected an erroneous Nautobot API PATCH request and strengthened API error logging/handling to improve troubleshooting. Overall impact: more reliable lifecycle automation, faster tenant onboarding, and improved observability, with strong signal for business value and engineering quality. Technologies demonstrated: Python, OpenStack Neutron, RBAC policy enforcement, REST API integration, advanced logging/diagnostics, error handling, and type annotation improvements.
