Hi, I'm Denis

I'm currently finishing my Master's in Computer Science at Karlsruhe Institute of Technology (KIT). Previously, I worked as a Security Engineer and spent some time abroad at CMU doing research. I'm particularly interested in offensive and defensive cybersecurity and artificial intelligence.

Feel free to reach out on any platform!
