Hi there, I'm Ümit! 👋

Computer Engineer | Software Developer

Computer Engineering graduate based in Ankara, Turkey. I enjoy working across different domains — from kernel-level networking to cryptography to AI-powered detection systems. Published researcher with a focus on chaos-based encryption and steganography.

I build tools that solve real problems and publish them as open source.
