Jeff Katz

Software / Hardware Engineer

In German, you might call me an "Eierlegende Wollmilchsau". It means, literally, "Egg-laying wooly milk pig" — the whole farm in one animal.

Why? I like working on difficult problems, and I often find myself having a hand in many different things at once. I've been known to tackle: Industrial design, mechanical and electrical engineering, electronic hardware development, firmware, communications protocols, software, web, mobile... I have a vast and varied experience, and I like getting my hands dirty.
