About Me

Security Engineer specializing in Digital Forensics & Incident Response (DFIR), with hands-on experience in malware analysis, threat hunting, and building detection capabilities.

I spend my time analyzing real-world threats, reverse engineering malicious payloads, and developing forensic methodologies that actually work in production environments. When I'm not investigating incidents, I contribute to the security community by authoring challenges for national-level competitions and sharing research on emerging attack techniques.

The writeups on this blog document my analysis of real attack patterns, forensic techniques, and security research.
