~/about_me

I'm a Software Engineering student at UTS specializing in offensive and defensive security application development. My primary focus is on developing security tooling, exploring encryption methodologies, and analyzing system vulnerabilities.


When I'm not studying or building custom infrastructure, I'm learning Rust and how to develop and use secure tooling related to it. Eventually I would like to port all of my existing portfolio projects to rust, but first, I want to make sure I have a good grasp of the language. I also enjoy periodically maintaining / updating my existing projects when I have good ideas for them or I discover a vulnerability.


As you will see with some of my projects below, I am a strong believer in online privacy, security, and anonymity, and related open source projects. I try to contribute to these projects when I can, as I believe what they are doing is critical. My contribution history is avaliable on my GitHub.
