What I'm looking for

I'm looking to continue building and securing high-availability Linux/Unix infrastructure, applying automation, disaster recovery, vulnerability remediation, and cybersecurity research in mission-critical environments.

At Digital IT LLC (HCL America), supporting Deutsche Bank, I administer high-availability RHEL, IBM AIX, and SPARC Solaris environments across physical and VMware infrastructure while maintaining 99.9% uptime.

I manage enterprise storage with LVM, Veritas Volume Manager, and ZFS; lead Unix troubleshooting and disaster recovery simulations; and co-led a Solaris 11 migration with zero data loss and minimal downtime.

I strengthen guest OS security through patching, kernel and firmware upgrades, vulnerability remediation, SELinux, Firewalld, and centralized SSH key management. I also build Bash and Python automation for system health and network monitoring.

My cybersecurity background includes ethical hacking, CTF platform administration, malware reverse engineering, digital forensics research, and peer-reviewed work on secure drone video transmission and steganography.
