Worked with big financial, e-comerce, medical business players to improve their development process and help to convert their ideas into implementation. "Fast food is cheap. It’s the same everywhere. Any fool can be taught to make it." I am not in the fast food business. I am a chef. I juggle Apple, clients, changing HIG guidelines, changing SDKs, tools, documentation… I design good layouts. I think through small-screen UI design. I pay attention to battery life. I look at what the client wants and I see past the requirements and into the real business problem. I anticipate what they really want, and I find the right balance between features and complexity.
