At MUFG Union Bank, I administer RHEL 7/8/9 production servers, automate operations with Bash and PowerShell, and strengthen security through patching, access control, STIG configurations, and incident investigation.
I've also supported Linux infrastructure at Marriott Hotel, configuring network services, monitoring performance with Nagios and Cacti, and improving reliability across remote sites. My background includes WebLogic, Apache HTTPD/HTTPS, VMware, AWS, Azure, and end-user IT support, backed by CompTIA Security+, CompTIA Linux+, and AWS Certified Solutions Architect – Associate certifications.
