Hey, I'm Tufan!

I'm a design engineer: I design products and build them myself. Since 2020 I've been a Product Designer at 4PLAY (Turkcell Group), leading UI/UX for apps like BiP, Paycell and 1GB, used by millions. I also co-founded TAO STUDIO, where we design, build and ship our own apps.

I shipped KimGBister (1M+ users) and Turn Out the Lights (250K+ users). I build with SwiftUI, React and Next.js, work with AI agents every day, and care about gamification, growth experiments and the craft where design meets engineering.
