Ex-GovTech (GITSIR) malware analyst, now Y1 CS at NTU (cybersecurity). I build and operate Atlas (Automated Malware Analysis Pipeline) and Mainframe (OAuth 2.1 Identity Provider) as part of SZEJO — production services I run, not demos on a slide.

I document everything I build here — architecture decisions, incident notes, build logs.
Y1 Computer Science @ NTU Singapore, specialising in cybersecurity.
Before NTU, I interned at GovTech (GITSIR) doing malware analysis — that's the work that got me hooked on this field.
I don't wait for opportunity to teach me things. I build systems, break them, fix them, and document everything.
I write the messy middle in the journal — #lessons, #execution, scope creep, small wins — not a highlight reel.
I built SZEJO — a lifelong cybersecurity project that I operate as a real production system. Every component is designed, architected, and run by me.
I'm available for freelance security work.
SZEJO is my production cybersecurity ecosystem — the services I design, build, and operate, and the control plane every one of them runs behind. Each is also available as a service or consulting engagement.
