I was invited to speak at APIdays in San Francisco. This was a local event. The event gave me a free ticket, and I was not paid to speak. The event did not pay for my travel and accommodation. My employer paid all of my travel expenses, and I was working while speaking at the event. It took me 2 days to prepare for my 24 minutes speaking slot, and I had a great time. I'm a man who has been speaking for 10 years. This was a not for profit event. Also, I love the crowd coming to this event and I had been attending the previous year.
