Profile Professional Profile

System & Network Administrator with a focus on reliability, security, and clear documentation.

Accustomed to SMB and multi-site environments, I handle network configuration (VLAN, VPN, Pro Wi-Fi), Windows/Linux administration, 3-2-1 backups, and efficient monitoring.

I am primarily looking for serious technical environments that prioritize simplicity, predictability, and clean deliverables.

I remain open to various arrangements:
team integration (employee), targeted mission, or project collaboration.
