Currently working as a game designer and developer my skill set focuses mostly on programming but often I find that on the projects I work on I end up taking on a lot of the tasks. There are four games under my belt with another three currently in development right now. One is contract work for a game studio and the others are personal projects as I try to expand and push my talents. I have worked on UI, VFX, and pixel art as well but most of my experience is in game mechanics, systems, and level design with all the programming associated with that. C# and C++ are my most commonly used languages with some time spent in Java-script as the platform for the contract work is in the Android/IOS space. I learn quickly and will do a good job, that I guarantee.

I'm a visual artist and can work fluidly across the digital landscape. I love making new logos, designing characters, illustration, comic art, and animation. Whatever your project is, chances are good that I have experience doing something like that. When I'm not making art, I'm either sharpening my skills or making more art. I would be honored to help bring your idea to life.
