About Me

Born in Novi Sad, Serbia, I developed a passion for technology from an early age. After attending the prestigious Gymnasium "Jovan Jovanović Zmaj" with a focus on IT, I moved to Germany to pursue a degree in Cybersecurity at DHBW Stuttgart.

I am an active Linux user and enjoy exploring system internals, networking concepts, and security challenges. My goal is to combine technical expertise with real-world problem solving to contribute to a safer digital world.
