About me

Hey! I'm Doruk, a Computer Science student at FHNW. When I'm not in class, you'll find me working as a Cyber Defense Engineer at MGB, where I help protect Switzerland's largest retail company from digital threats.

But I don't just code for a living! I also produce lofi music that's been listened to by millions of people on Spotify, coach table tennis to at the largest academic club in Switzerland, and build AI Tools that make life a little easier.

My journey started with web development, evolved through digital marketing, and led me to co-founding my own label, Soothe Records. I thrive on learning new things and turning challenges into opportunities. Whether it's debugging code, crafting melodies, or building something entirely new.
