Rotterdam, 29 May 2015

Welcome to Joy of Coding! A one-day conference celebrating the art, craft, science and joy of software development.

The next edition will be held 29 May 2015 at the Van Nelle ontwerpfabriek in Rotterdam. Reasons why you should attend:

Learn new stuff

We're not happy unless you go home after Joy of Coding feeling inspired and full of new ideas. That's why we're cramming the conference full of renowned speakers, passionate developers like yourself, and (un)sessions that we hope you'll love.

Great value

We know you can't go to every conference every year, but we really want you to come to ours, so we're working to keep the entry price completely reasonable by teaming up with sponsors. Our goal: be the best value for money conference in 2015. Our very-early bird tickets start selling at the meager price of only EUR 128,-!

By devs, for devs

Like you, we're a bunch of developers who like going to interesting conferences and meetups. So there will be no commercial agenda or ulterior motive to Joy of Coding. It's just a place where we can all get together and talk about code.
