Art Director & Programmer

Istanbul ↔ Moscow

Hey, I'm Hasan — but most people know me as rentonhead. An Art Director and Programmer based between İstanbul and Moscow.

I bridge the gap between design and development to build modern digital products. On the technical side, I create mobile applications with SwiftUI, web experiences with React & Next.js, and robust e-commerce solutions.

On the creative side, I craft visual identities and seamless UI/UX designs using Figma and the Adobe Creative Suite. I love turning abstract ideas into functional, aesthetic, and meaningful digital experiences.
