01 / About
About me
I'm a Computer Science (Cyber Security) student at the University of Wollongong, building on a Diploma in Cybersecurity and Digital Forensics from Temasek Polytechnic.
My projects range from a security toolkit with malicious-download scanning and facial recognition, to an encrypted password manager and a Telegram bot that tracked my National Service company's daily strength.
Before university I served two years of National Service as a section commander in the Infantry Training Institute's Opposition Force, and earlier, in secondary school, led as Regimental Sergeant Major in NCC Air.
