I proposed an idea to speak at JSCONFCo in Medellin, 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 did not pay my travel expenses, and I was working while speaking at the event. It took me 30 days to prepare for my 25 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 1 year. This was a not for profit event. Also, Great experience. The trip was exhausting but I am so glad I went. Would gladly recommend to others.
