United StatesWhat I'm looking for
I’m a Mainframe Security Engineer with a strong focus on RACF administration and cybersecurity within government systems. I manage user access provisioning, security compliance, and security operations, and I help teams improve access management while mitigating risks through validated, SOP-aligned changes.
Over multiple years supporting OPM as a US government contractor, I’ve facilitated RACF security group creation, new user account provisioning on ESI mainframe platforms, and ongoing account modifications (including monitoring expiration dates for contractors and limited access). I also contribute to z/OS/z/VM/UNIX configuration work, Digital Certificate support, Connect Direct request processing, incident troubleshooting, and audit-ready artifacts to strengthen compliance and operational continuity.
