I proposed an idea to speak at KiwiParty in Strasbourg, so I travelled domestically to speak. The event asked me to buy a ticket at full price, 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 7 days to prepare for my 20 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, This event is great for front-end and CSS lovers.
