I am an entry-level Network Engineer and Linux enthusiast with a strong interest in network security, enterprise routing & switching, and infrastructure automation. My journey began with experimenting on Linux server administration and dissecting network traffic, which quickly evolved into a dedicated pursuit of building and hardening network environments.

I am actively seeking entry-level Network Engineering opportunities where I can leverage my hands-on skills in Cisco Packet Tracer / GNS3 lab design, subnet planning, WireGuard VPN configuration, firewall rulesets (pfSense/OPNsense), and packet inspection to deliver reliable, secure network operations.
