Kerem Yokuva

I wrote my first program in 1985, at ten.

Forty years later I still build every one of my games myself: design, code, art and release.

Games and apps

Everything I've published on the App Store, in the order Apple lists it. I designed and built each one alone. Pet Play Date, at the top, is a Mobil365 app where I'm the product owner.

About me

I'm Kerem Yokuva, a game developer in Istanbul. I wrote my first lines of code in 1985, when I was ten, and I've been programming ever since.

I turned professional in 1998 and started making games in 2002. Since 2012 I've designed, coded and published 22 games and apps on the App Store, every one of them as a solo developer: reflex games like Ztap Bird, the Space Defense shooter series, word games in Turkish and Finnish, and puzzle games like Deflector with AI-generated levels.

Today I'm a technical consultant at Kurumsal Bilişim Çözümleri (KBC), the company behind Mobil365, where I decide the technology stack, backend and frontend, for the company's projects. Before that, alongside my own titles, I worked as a senior Unity developer for Azerion (Habbo, Troll Face Kart Battles), Joygame (Desert Warrior) and Mafia Games (Fashion Challenge, 1001 Puzzle).

Four decades of coding means I've seen most problems before. From game design and C# in Unity to 3D art, optimisation, servers and release pipelines, I handle the whole thing end to end.

I came to games through architecture: my master's at Istanbul Technical University produced a raytracing engine for architectural models.
