Blue teamer by day,
community builder by night.
I build automation pipelines, detections and run incident response at Gamuda, do cybersecurity research on the side, and I founded SherpaSec, one of the biggest cybersecurity community for practitioners and students in Malaysia. Free to join, vendor-neutral, always technical.
Alongside that I instruct and deliver talks on automotive hacking and AI security, while serving as a speaker and panel for various events, including CYDES and DEFCON.
