About

I break into secure systems to find flaws before the bad guys do—and then I teach organizations exactly how to fix them. My career in IT started in 2010, evolving into full-time offensive security and pentesting in 2017. Today, as a CISO and IT Security Consultant at Securitum & Sekurak.pl, I seamlessly bridge the gap between hands-on technical hacking and executive-level security management. I consider myself a lifelong tech enthusiast with a deep love for Linux, automation, and networking protocol analysis. But my favorite challenge? Translating complex, terrifying technical concepts into accessible, human language. Where you can find me: - In the trenches: Executing comprehensive pentests across web apps and network infrastructures. - In the boardroom: Advising organizations on high-level defensive strategies. - On stage: Sharing industry insights at Infoshare, MEGA Sekurak Hacking Party and others, instructing the next generation of security professionals at Sekurak.Academy. I use LinkedIn to share my daily thoughts, industry insights, and real-world security lessons. Let's connect!
