The context
Central university services ran across IBM Power/AIX, Oracle E-Business Suite, Oracle Student System and heterogeneous Unix, Linux and Windows environments.
My responsibility
As a Senior Network, Server and Security Specialist, I combined technical architecture, operational support and staff/project management. The work required understanding the application, identity, infrastructure and security layers together.
The work
Designed and implemented federated identity integration using Kerberos and SAML/Shibboleth, and tuned application-layer security controls for Oracle services. Contributed to active-active infrastructure across two sites.
Shared infrastructure
Designed and implemented migration of application workloads to VMware, with shared provisioning and cost allocation for authorised University users.
