hello, i'm charles.

i like learning how things work — and how they break.

I'm studying Cybersecurity & Digital Forensics at Nanyang Polytechnic. This is a small collection of things I've worked on, learned, and built along the way.

about

Most of what I enjoy is hands-on: setting things up, finding out why they don't work, fixing them, and understanding what went wrong in the first place.

I spend most of my time around cybersecurity, networking, Linux, virtual machines, Python, and small web projects. I also hold ISC2's Certified in Cybersecurity certification.
