About Me

I am a Computer Engineering graduate specializing in Offensive Security and Red Teaming. My technical focus centers on dissecting network protocols, Active Directory domain architectures, and authentication mechanisms to identify structural weaknesses before malicious actors can exploit them.

Operating within self-built, isolated virtual lab environments, I conduct end-to-end assessments spanning deep enumeration, Kerberos exploitation (AS-REP Roasting, Kerberoasting), credential attacks via Impacket, and low-level traffic manipulation using mitmproxy scripting and ARP poisoning workflows. I bridge fundamental networking concepts (TCP/IP, TLS handshake, OSI layers) with practical attack chains to understand not just how an exploit triggers, but the exact protocol exchange occurring under the hood.

Driven by an analytical, root-cause mindset, I am committed to advancing my technical craft through rigorous hands-on exploitation, lab research, and offensive engineering.
