Orkun Eser Kadan

Mobile game & app developer · Kocaeli, Türkiye

Hi, I'm Orkun. I make mobile games. I started out at my own company, doing everything myself, from design to store publishing and marketing.

After that I worked at game studios in Istanbul. At Talus Studio I led a team and built the framework used across all of the studio's games. I taught Unity to about 40 people at Robot Dreams, and I co-founded Grus Games, where we tested game prototypes with publishers.

Today I build games and mobile apps for people and studios, and also help with store publishing and ads. AI tools are part of my work every day.
