01 · About

Infrastructure, built to be trusted.

I work across self-hosted and cloud environments — designing endpoint security architecture, standing up SIEM and MDM stacks, and automating backups you can actually trust. My home lab doubles as a proving ground for enterprise networking and virtualization patterns before they ship to production.

02 · Experience

Keeping delivery reliable.

Production operations, automation, and security work across cloud and container platforms.
