Hello, I'm
Wai Hoi
A computer science student at Singapore Management University, specialising in cybersecurity. I enjoy understanding how software is built, and how it holds up when things go wrong.
About
I come from a networking and software engineering background. Through internships in Singapore, Indonesia and Vietnam, I've built APIs, designed database schemas and shipped features for real clients. That work taught me how applications fit together, and where they tend to break.
Today I'm focused on security: learning through pwn.college, working toward my OSCP, and taking part in CTF competitions. Outside of that, I'm always keen to try new fields and keep learning.
