Over the span of 10+ years of professional experience, I've seen my fair share of good ideas and projects go to waste because of bad presenting. Entrepreneurs, innovators, professionals don't care or don't know how to prepare a deck and therefore make a good idea sound mediocre.
The way you express yourself is just as important as the work itself. I believe presentations must be simple, engaging, and come with a clear message. Below are sample slides I put together for various occasions.
Presentation: UX Design Fundamentals
Presentation: Redesigning Public Bikes Web Site
Presentation: Investor Pitch for Workbuk
