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 hold CompTIA Security+ and ISC2 Certified in Cybersecurity certifications.

community
project rejuvenaid.
As a Lumina Fellow at Nanyang Polytechnic, I joined Project RejuvenAid, a community volunteering initiative that brought us together with seniors through conversation, shared meals, and companionship.
It reminded me that giving back doesn't always have to be complicated. Sometimes, showing up and taking the time to listen can mean a lot.
