Summary
👤
Senior🎓
Top SchoolSam Morrison is a Technical Lead with 18 years' experience designing, operating and hardening OpenStack-based research clouds, currently leading the NeCTAR Research Cloud nodes at the University of Melbourne. He combines deep Linux systems administration and security expertise with hands-on Python/Django development to build resilient cloud and identity services. A consistent backend contributor to core OpenStack projects (ceilometer, cinder, nova, horizon, trove), he focuses on telemetry, block storage, compute and DBaaS reliability and interoperability—often solving nuanced edge cases like cross-AZ volume checks and Glance HTTPS integrations. His background running national grid infrastructure and federated SSO gives him a pragmatic view of large-scale academic and research environments. Sam is as comfortable refactoring scheduler logic and metadata handling as he is tuning database drivers and template tests, bringing both operational discipline and developer empathy to platform engineering.
