About

I'm a Lead Penetration Tester at Mantel Group doing all things offensive security. I have a strong passion for all things security whether that includes self-learning, participating in CTFs or actively attending local meetups and/or conferences. This passion has also lead me to be the founder of an online CTF and non-for-profit called DownUnderCTF. In 2023 (fourth consecutive year), the competition had over 4200+ registered players and 2000+ registered teams making us the largest CTF ever run in Southern Hemisphere.
