About

A brief introduction.

Hi — I'm JC. I work as an Associate Cybersecurity Specialist at GovTech Singapore, where I help secure Singapore's Government Digital Services through SAST/DAST, penetration testing, and DevSecOps practices.

I hold a B.Tech in Computer & Information Systems Security (Honours, Distinction) from the National University of Singapore, and certifications including CISSP, CompTIA Security+, and AWS Certified Solutions Architect. Prior to GovTech I spent nearly three years at Accenture across security analyst and IAM roles, and before that built GIS applications at Esri Singapore.

Outside of work I volunteer with the Singapore Computer Society, having served on the IT Youth Council and led the Digital Youth Ambassador programme. When I'm not doing any of that, you'll find me deep in a YouTube rabbit hole.
