Cybersecurity Engineer Penetration testing, vulnerability assessment, network security
I spent four years attacking identity. Now I defend it.
I am a cybersecurity engineer based in Indonesia. Most engagements start the same way: someone points me at a system they already trust and asks what happens when that trust is wrong.
At Intelix Global Crossing I ran technical discovery with clients, scoped the work, executed the testing, and turned the results into commercial proposals. At Brawijaya University I focused on network security and systems analysis, and taught Operating Systems as a laboratory assistant.
Outside work I run the security track at POROS, the open source organisation of the Faculty of Computer Science — currently Head of Internal, after two years in public relations.
