About Me

I am a passionate cybersecurity enthusiast and AI student pursuing my Master's degree in Artificial Intelligence at BTU Cottbus. With hands-on experience in ethical hacking, penetration testing, and machine learning, I'm dedicated to building secure and intelligent systems. My journey spans from CTF competitions on HackTheBox and TryHackMe to developing security tools and analyzing complex datasets.
Currently based in Berlin, I combine theoretical knowledge with practical skills in Linux system administration, network security, web application security, and data analysis. I'm always eager to learn new technologies and tackle challenging security problems.

🐾 In Loving Memory of Zeus 🐾

Zeus - Our Beloved Cat
2021 — December 15, 2024
Zeus

Our Beloved Companion

Zeus was more than just a pet—he was family. With his gentle spirit and loving nature, he brought countless moments of joy and warmth into our lives. Whether curled up on a sunny windowsill, purring contentedly in our laps, or greeting us at the door with his unique meows, Zeus reminded us daily of the simple pleasures of unconditional love.

His legacy lives on in our hearts and in the memories we shared. The love we had for him is eternal, and we will forever cherish the years he spent by our side.
