About

Cybersecurity isn’t just a job for me - it’s a craft. I specialize in identifying and resolving complex security vulnerabilities, with hands-on experience across offensive and defensive security. I hold certifications including OSCE³ (OSEP, OSWE, OSED), OSCP, CRTO, CRTL, and CRTE, which reflect both deep technical knowledge and a commitment to continuous learning. My work ranges from reverse engineering and red teaming to advanced attack simulations - all with the goal of helping organizations stay ahead of evolving threats. I believe in building security that’s proactive, practical, and rooted in real-world tactics. At the core of everything I do is a focus on trust, integrity, and staying sharp in a field that never stands still.

Blackbar - Destroy secrets in screenshots - Mac & Linux & Windows

Report screenshots are full of client secrets — internal IPs, hostnames, creds, tokens, hashes — that can't ship in a deliverable, so you black them out by hand, one by one, hoping you didn't miss one. Blackbar finds them automatically and destructively burns them out (opaque bar into a fresh bitmap, metadata stripped — not a blur you can undo), keeps the same value labeled the same across every screenshot, and runs 100% offline. macOS; Windows; Linux, $19 once.
