Codemotion Amsterdam 2018, day two

Codemotion Amsterdam 2018, day one

Last Friday I almost felt I had to explain a colleague that I don’t always win raffles and lotteries. Because yep, I won another ticket. Again via the Roaring Elephant podcast. It’s pretty worthwhile listening to them, is all I’m saying.

This was a ticket for CodeMotion Amsterdam 2018. CodeMotion is a conference for developers with topics like the blockchain, Big Data, Internet of Things, DevOps, software architectures, but also front-end development, game development and AR/VR.
