Justin Gottschlich

WELCOME

I am a principal software engineer at an exciting and fast-paced startup company in Palo Alto, called Machine Zone. My primary area of work at Machine Zone is in the area of mobile game design and development, with a specific emphasis on massive scalability for social gaming. If you have interest in scalable mobile game development, or know someone who is, please contact me at jgottschlich@machinezone.com.

I also hold an appointment as an adjunct professor at the University of Colorado-Boulder in the department of Electrical, Computer, and Energy Engineering. For over a decade, I have run my own software company, Nodeka, LLC., of which I am the founder and CEO. Previously, I was a staff research scientist in the Programming Systems Lab at Intel Labs, Intel Corporation.

My CV can be found here.
