About

Leading Advanced-Technology Electronic Product Development and Global Production. Interested in working with established companies as well as funded startups worldwide.

I am fueled by coffee. If you found anything that I have created useful, interesting or whatever, feel free to buy me a coffee. Or not, it's fine either way, but ALWAYS appreciated.
