Undergraduate researcher and defensive security engineer focused on digital forensics, proactive threat detection, and resilient system infrastructure.
I'm Ahmad Rafi Sutanto, a Cybersecurity undergraduate at BINUS University specializing in Blue Team operations, Digital Forensics, and Threat Detection.
Currently serving as Deputy Coordinator of R&D at Cyber Security Community (CSC) and Apprentice at PETIR Cyber Security, where I architect automated CI/CD security infrastructure, orchestrate competition problem sets, and dissect low-level kernel and memory telemetry.
