Cyber Security
AI Security & Engineering
In one of Europes largest tech companies, I develop AI agents and Retrieval-Augmented Generation (RAG) systems to automate cybersecurity workflows, while also researching the latest AI vulnerabilities and adversarial attacks to stay ahead of emerging threats.
Offensive Security
At one of Germany’s leading banks and later at one of Europe’s largest software companies, I conducted penetration tests for web applications and carried out in-depth code reviews. These projects sharpened my ability to uncover vulnerabilities across both application code and system infrastructure.
Defensive Security
While working in a Security Operations Center, I developed threat detection rules and enhanced the SIEM stack to strengthen monitoring capabilities. I also proactively hunted for threats and built Python tools that integrate multiple CTI services, streamlining investigations and improving threat visibility.
