I design products — and then I build them.
I’m Selim Yaylali, a product designer and front-end engineer in Istanbul. I work at Doğuş Teknoloji, where I was the sole designer on BadgeForce: its design system, its mobile app and admin dashboard, and the robot characters that carry its game loop.
I studied Software Engineering, and I still build what I design. My graduation project, PetsConnected, was a React Native app I designed and built end to end.
I like taking a brand the whole way. For PACT Media in Stockholm I drew the identity, designed and built the bilingual website, set up its hosting, and made the 62-second film that launches it.
Away from the screen I sail, travel, and DJ now and then.
