About me

Defending systems.
Thinking like an attacker.

I'm a cybersecurity & IT professional based in Melbourne, Australia, with a background in Information Systems Management and hands-on security training. I completed Monash University's intensive 6-month cybersecurity bootcamp and earned CompTIA Security+ certification in January 2025.

My practical skills span SIEM operations with Splunk & Wazuh, network reconnaissance, digital forensics, and incident response. To bridge the experience gap, I'm extensively building homelab projects — deploying real security tools in virtual environments to develop production-level skills.

Open to entry-level cybersecurity roles, entry-level IT roles, and internships where I can contribute from day one and grow within a team.
