About

I study how systems fail so I can help build ones that don't

At UTS that means a cybersecurity and networking major, with Python, C/C++, machine learning and data science picked up along the way. The rest of the week I teach kids to code at Code4Fun. Demos like the one above are how I explain concepts to people unfamiliar with the specifics!

I’m aiming for a career in offensive security, most likely penetration testing or security engineering, and I’m looking for graduate roles or internships where I can learn from people who do it well. I finish my degree in 2027.
