Tobias Wehrum

Freelancing Game Developer

I'm a freelancing game developer with specializations in both Unity3D/C# and full-stack web development (JavaScript/TypeScript, WebGL, PixiJS, PlayCanvas, React, Node.js, and a master's degree in International Media and Computing.

I make games and apps for:

  • Desktop, AR/VR, Android and iOS (with Unity3D/C#)
  • Web frontend and backend (with TypeScript, WebGL, React, PixiJS, PlayCanvas, Node.js,

During the last 10 years as a freelancer, I worked on many different projects:

My passion for game development shines through while I'm off the job too: I co-founded the monthly Berlin Mini Game Jam which I co-organize for over 12 years now and I create a lot of game prototypes and smaller games in my free time. Years of experience make me very fast at rapidly sketching out game ideas into prototypes. My curiosity and my eagerness to learn new things ensure that I'm staying up to date with recent developments and technologies.

I love experimenting, be it with gameplay or with technology. I've worked with Augmented and Virtual Reality, alternative input methods (e.g. huge multi-touch tables with object recognition, Microsoft Kinect, Leap Motion, voice-controlled games) and I've built alternative controllers and game installations myself. I like making generative art and I am also pretty interested in AI, electronics and the maker movement in general.
