​PLRUG Ruby Warsaw Hackathon

​This time, we’re doing something a little different.

​Instead of our usual PLRUG Warsaw meetup format, we’re inviting the Ruby community to spend an evening building, experimenting, and solving a challenge together.

​Join us for a hands-on Ruby hackathon at the Visuality office in Warsaw.

​What to expect

​The hackathon will last 4 hours and will take place in a friendly, informal setting. You’ll work on a challenge prepared by us, but the exact topic will be revealed only on-site.

​No spoilers for now, but you can expect something fun, practical, and Ruby-related.

​You don’t need to prepare anything in advance. Just bring your laptop and curiosity.

​We’ll take care of the rest: coffee, drinks, food and a comfortable space to work in.

​Important: limited capacity

​This is not a regular open meetup.

​Because of the hackathon format, we can only host 20 participants.

​Please register only if you’re planning to attend. Your registration means taking one of the limited available spots.

​If your plans change, no worries - just cancel your registration as soon as possible so someone from the waitlist can join.

​After the hackathon

​The official part ends at 22:00, but if the weather and the group are up for it, we’ll continue the evening somewhere nearby by the Wisła - with space for relaxed conversations, networking, and hanging out with fellow Rubyists.

​Who is it for?

​This event is for people who enjoy Ruby, Rails, programming, learning by doing and spending time with a friendly tech community.

​You don’t need to be an expert to join, but you should be comfortable enough with Ruby or Rails to participate in a hands-on coding session.

​Come build something with us.
