I proposed an idea to speak at JSConfEU in Berlin, so I travelled internationally to speak. The event gave me a free ticket, and I was not paid to speak. My travel and accommodation was fully covered by the event. My employer paid some of my travel expenses, and I was working while speaking at the event. It took me 14 days to prepare for my 25 minutes speaking slot, and I had a mostly good time. I'm a man who has been speaking for 3 years. This was a not for profit event.
