Bill is a phenomenal game designer, and that's not an adjective I use lightly.
When we first interviewed Bill, a creative director friend of mine noted that "he was the best system designer I've ever worked with," and Bill lived up to those expectations.
He has a deep understanding of the inner workings of game systems, how they mesh with various launch, gameplay, product, and monetization strategies, and has an ever-updated knowledge of current trends in the industry.
I wholeheartedly recommend Bill.
“Bill is a rare gem of a Principal Designer. Deeply thought out systems and designs, clever, elegant solutions to tough problems.”

Bill is a rare gem of a Principal Designer. Deeply thought out systems and designs, clever, elegant solutions to tough problems, and a wealth of experience. Even coming back to refine subtle things in designs as he's constantly thinking about it making sense as whole.
He is a great guy to work with and just a great guy to KNOW. I would work again with him in a second, and if I get my next thing going, I will hire him, so if you wanna steal him from me, here's your shot. Get this amazing designer in your team!
I make stuff too!
