Thank you for visiting my homepage!

I am a 33-year-old hacker from Germany who is passionate about cybersecurity and driven by the constant challenge to stay one step ahead and to play outside of my comfort zone.

After completing my Bachelor's degree in IT Security, I started my professional journey as a penetration tester at TÜV Rheinland i-sec GmbH. During this time, I gained hands-on experience in identifying vulnerabilities, securing complex infrastructures and helping organizations improve their security posture.

However, my desire to develop professionally and personally has led me into self-employment to offer my clients a more personalized and tailored approach. Whether you are a company looking to improve your security, a professional colleague interested in sharing experiences, or simply someone curious about cyber security, get in touch with me. I'm always happy to help, collaborate or simply share ideas.
