Hi, I'm Onur! I'm a Solopreneur and the Founder of Headon Kreativagentur(headon.pro), a next-gen digital agency. I design and engineer high-performance web applications, interactive 3D scrollytelling experiences, and custom AI-accelerated workflows. What I'm currently building & scaling: Rechnerzentrale.com a massive, ultra-fast suite of 190+ smart calculators (bringing regional tax & daily-life logic to Expats in English!). Aphantasie.org a multilingual platform & custom-built Three.js/WebGL experience exploring the spectrum of visual imagination. I build everything solopowered by a custom system of 12 specialized AI agents. This allows me to deliver enterprise-grade performance, 60 FPS mobile WebGL, and lighting-fast deployments for both my own products and my B2B clients.

Mind Atlas - Map how your mind works: imagery, memory, inner voice

Some people see vivid pictures when they close their eyes, others see nothing. Mind Atlas turns five short self-tests (visual imagery, the other senses, autobiographical memory, inner voice and a perception experiment) into a living map of your mind. After three you meet your archetype, after five your atlas is complete, with a Full Mind Report that is free during our pilot. No sign-up, and your answers never leave your browser. In 5 languages.
