Offensive Security & Technical Research Portfolio
Report Writeups View Certifications

Offensive security practitioner and student focused on Active Directory, enterprise networks, and internal network exploitation. Over the past couple of years, I've built a strong skillset through hands-on labs, structured training, real-world style engagements, and certifications, including the PNPT, CPTS, and OSCP+ (in progress).

My appoach is centered on understanding how attackers actually operate in real-world environments. I prioritize practical methodology over theory, with a strong emphasis on enumeration, lateral movement, and privilege escalation.

I believe that all knowledge is worth having. This site is meant to document and display my penetration testing reports, various projects and tools, and ongoing technical research as I build a career in offsensive security.
