Industrial Design Engineer, Singer, UI/UX expert, Dancer, Developer, Writer, and more.

Ana: I’m going to Germany for a month.
Me: What? Why?
Ana: I’m very distracted by my friends. I need to disconnect to be more productive.
Me (after thinking for some hours): You’re crazy. Can I interview you?

To tell you this story, I would like to first travel a thousand years in the past, to Zhenjiang, China.
