Summary
With years of extensive experience in cybersecurity, I began my journey as a penetration tester, later advancing to the role of a senior security analyst. My career then took me to the management level, where I served as an Information Security Officer for a global enterprise.
Following this, I transitioned into independent freelance consulting, specializing in short-term projects and consulting opportunities. I hold numerous certifications, including GIAC Certified Detection Analyst (GCDA) and CompTIA Advanced Security Practitioner (CASP), and I am skilled in Python and various security tools. My commitment to cybersecurity extends to volunteering as a lecturer for Czechitas, where I play a vital role in raising cybersecurity awareness.
Furthermore, I am a vetted expert within global expert groups, such as the United Nations Development Programme's Roster and EU CyberNet, showcasing my exceptional expertise and dedication to advancing cybersecurity on a global scale.
I always seek new consulting opportunities. Looking forward to meeting you.
