Cybersecurity student and systems administrator with 5+ years of technical experience, focused on authorized penetration testing, vulnerability discovery, security automation, and defensive validation.

My work centers on understanding how systems fail, validating risk with evidence, and turning findings into clear technical documentation. I build hands-on labs, automate security workflows, and continue developing a repeatable penetration testing methodology grounded in scope, evidence, and responsible testing.
