Buffalo, NY Systems administration & enterprise automation
Systems administrator.
Enterprise automation practitioner.
Mainframe operations apprentice.
I automate operational work, build resilient infrastructure, and document systems so they can be maintained and recovered.
Professional focus
I'm a systems administration and automation professional currently apprenticing in mainframe operations at M&T Bank, with hands-on work across IBM z/OS, OPS/MVS, Broadcom Watchtower, and Ansible Automation Platform.
My broader experience spans Linux, network infrastructure, security controls, Docker, Proxmox, and technical education. I teach at Trocaire College and build practical labs that connect technical concepts to operating systems.
As an active member of BitHaven hackerspace, I collaborate with fellow security enthusiasts on research projects, CTF competitions, and community workshops.
My background spans IT management, cloud computing, and security implementation. I believe in hands-on learning and building real-world skills that translate directly to the workplace.
