Cybersecurity Engineer

I secure systems
by understanding
how they break.

Cybersecurity engineer at Politeknik Negeri Batam. I build software, dissect architectures, and visualize complex attack chains. Because security should be accessible, not obscure.

Philosophy

To truly secure a system, you have to know exactly how it breaks. And to break it effectively, you first need to understand how it was built.

I operate on both sides of the spectrum. I build functional software like the AI-powered 'Voice POS', but I also love tearing down architectures to discover their hidden weak spots. As a 6th-semester student at Politeknik Negeri Batam, my focus is bridging the gap between textbook theory and practical real-world application.

From analyzing malware traffic to running full-scope penetration tests for academic institutions, I really enjoy the technical hunt. However, my background as an IT Support and Data Assurance Officer gives me a more pragmatic perspective on daily systems administration and how data protection actually works in the field.

I don't just write standard vulnerability reports. I prefer to visually map out my findings and translate complex attack chains into clear, actionable insights. Because at the end of the day, security should be accessible and straightforward, not confusing.
