Offensive insight.
Stronger defenses.

I secure real infrastructure and assess how its controls, trust boundaries, and applications fail.

I began in systems administration, where my work grew from keeping infrastructure operational to hardening Linux, Windows Server, and Active Directory environments, securing web applications, managing access, and responding to incidents.

That operational background defines how I approach security: understand how a system is built, trace where trust breaks, validate the weakness, and explain the real impact without losing sight of how the environment must continue to operate.

I hold the HTB CPTS and I am currently pursuing the HTB CWES to deepen my web exploitation skills. My focus is offensive security and red teaming, grounded in the discipline and accountability learned in systems operations.
