Welcome to Yobonja! We're a small group of game developers based in the San Francisco Bay Area dedicated to making fun and interesting experiences.

We also aim to be a resource for young developers. For now all we offer a collection of links to game development tools we like, as well as some developer resources we've made ourselves that hopefully might be useful. In the future we plan to offer tutorials on game related topics, source code to get started with and more game development tools of our own. So stay tuned!

I love making things, especially useful/fun/interesting things. I spend my time painting, coding, inventing and sometimes soldering. In 2009 I started Yobonja with Tobiah to put myself to work and make fun/interesting experiences. These are mostly games, but for example Vamp Yourself is a facebook app that sort of evolved out of my minor obsession with image filtering.

I love all things gaming. From computer games to boardgames and pen and paper RPGs. My favorite games are the Half Life series, The Longest Journey, and Dungeons and Dragons. Besides gaming, I also enjoy theme parks, B movies, and metal music.
