Systems online

Infrastructure, engineered.

Building resilient self-hosted systems from bare metal to cloud.

Journey

The stack I've built

Every tool, every pipeline, every cluster — from homelab to production.

Homelab & Storage

Enterprise-grade storage and virtualization running on personal infrastructure. Redundant backups, RAID arrays, and hypervisor management.
