I've completed 200+ hands-on penetration testing engagements across OffSec Proving Grounds, Hack The Box, TryHackMe, and Virtual Hacking Labs, building a repeatable troubleshooting and documentation methodology.

I administer Windows and Linux lab environments, troubleshoot hardware, software, and network configuration issues, and work with Active Directory user, group, share, provisioning, and access-rights concepts. My technical foundation includes TCP/IP, DNS, SMB, SSH, OS installation, driver setup, and custom PC builds.

I've earned OSCP+ with a 100/100 score in under seven hours, HTB CPTS, Security+, CCNA, and A+. I publish detailed technical writeups and methodology guides at freedie.org.
