Hello Ruby Enthusiasts!

It's time for the next KRUG meetup!

This time, we will have one technical talk... and something special :).

KRUG #2/2020 is powered by u2i (

u2i is a web technology consulting company established in 2000 in NYC and currently operating from Zabłocie in Krakow. They are 55 people strong with a flat structure, no managers, and 100% profit sharing. And while developing great code is in their nature, complex problem-solving and bringing ideas to life with tech is their true passion. For u2i, it’s all about the value for the end-user, close collaboration with the clients and finding creative solutions to their business needs.
