Server & Infra Architect | openSUSE Tumbleweed 🦎 | PADI Freediving Instructor 🀿


About Me

Hi! I'm a Server & Infrastructure Architect who builds, secures, and maintains enterprise-grade systems β€” from bare-metal servers to cloud endpoints.

My journey started with curiosity about how Linux works under the hood: not just using the CLI, but understanding how the kernel schedules resources, how device drivers communicate with hardware, and how security modules enforce access control at the system level. That curiosity turned into a career spanning ITSM operations, infrastructure engineering, and endpoint security across multiple industries including SK Group and global pharmaceutical enterprises.

I've managed the full lifecycle of 500+ corporate devices, designed ITSM workflows on ServiceNow and Atlassian, built automation scripts that eliminated hours of repetitive ops work, and operated 24/7 mission-critical server environments. On the side, I run a full-stack homelab (Proxmox, OPNsense, Podman, Synology) and an independent business providing SW/HW solutions.

When I'm not behind a terminal, I'm underwater β€” I'm a PADI certified Freediving Instructor, teaching students to push their limits safely in the deep.
