About
I am an experienced AIX Unix Administrator who worked at the University of Iowa Hospitals and Clinics, with a career spanning over 30 years since 1992. My work has involved supporting complex Unix environments, including AIX, Solaris, and Linux, across multiple industries such as healthcare, finance, and government.
My expertise includes managing AIX upgrades, HACMP clusters, Tivoli Workload Scheduler, and virtualization technologies like ESXI. I have built and maintained large-scale server infrastructures, automated system tasks with shell scripting, and supported enterprise applications including WebSphere and Oracle. I have also contributed to disaster recovery planning and performance monitoring using tools like Introscope and Tivoli Enterprise Manager.
