I'm your one-stop shop for 2D game development from concept & GDD creation, to a full game delivery. I've created over 250 web games for clients to date, as well as a variety of desktop (Steam) and mobile (Android & iOS) titles - with a speciality in advergames! My clients have included solo-indie devs all the way up to Fortune 500 companies.

I'm a professional developer with the Unity development engine. I've been using the engine since 2007, when I taught myself the engine to such a degree I paid my way through college by selling tutorials for the engine. (My old website for those is unity-tutorials.com, sadly now out-of-date) Starting in 2011, I began doing professional consulting and work-for-hire making games and software for smaller companies and individuals. Those projects ranged from a simple storybook app for iOS to the official software edition for "The Farming Game," a classic board game. I've also created more abstract apps like an educational program that tracks learning progress for middle-schoolers, a nuclear warhead damage simulator for a charity, and the 3D visualizer for Acupuncture of the ear (Auriculo). Since then I've worked full-time in multiple jobs including at Williams Interactive as an engineer creating slot machines, at Keystone Games as a lead programmer making computer games and fixing existing ones (I optimized and rebalanced the recent release of Rogue Islands over two weeks, for example), and at my current job with Level Ex, Inc. I'm fully capable to create any number of game systems and I'm skilled working solo or as part of a group. I also have extensive contacts with sub-contractors, so I'm able to take on much larger projects if needed. Thank you for your interest and I look forward to working with you!
