About
I’m Bahadır, an iOS software engineer and independent app developer based in Berlin, with eight years of experience building and shipping apps.
I work across Apple platforms with Swift, SwiftUI, and UIKit. My background spans consumer products used by millions and the complete lifecycle of my own shipped apps—from product thinking and interaction design to architecture, App Store release, and ongoing iteration.
Today I build iKeep, Bubbles, Ballance, and HealthBar, exploring practical ideas around privacy, focus, play, and everyday wellbeing.
