The Woodstock of Developers

Behind every amazing tech innovation today are developers – these unique creatures that are able to turn coffee into software, using code as their primary instrument. Since 2015, once a year, on a (hopefully) sunny day, the global community meets at WeAreDevelopers, an event dubbed by many as the “Woodstock of Developers”.

WeAreDevelopers World Congress 2018 brought together 8,000 techies from 70 countries for 72-hours of pure dev-fun, with more than 150 of the brightest minds in tech and the largest playground for developers in Europe.

Let’s be honest: attending workshops can be dull. BUT – not here, not with us, WeAreDevelopers! We combine expert knowledge with entertainment and industry know-how to deliver the workshop of workshops. It’s going to be so great; you will talk about it at the next workshop that is boring, saying something like, ‘Man, I’ve been at this WeAreDevelopers Workshop in 2019, and it was so great, this one sucks, why can’t every workshop be like the one from WeAreDevelopers?!’

You think you want to miss saying that? You think you want to miss the concentrated power of knowledge, entertainment, AND know-how? No?
We didn’t think so!

Join us at the WeAreDevelopers Congress 2019 and get into some workshops, baby.
