Data KRK brings practical Data Science to Krakow. It is everything you always wanted to know about Big Data, NoSQL or Machine Learning, but were afraid to ask.

Our main area of interest is Hadoop Ecosystem and bringing business value out of it, but we don't forget about anything related to Data Science.

Whether you just want to have a good time...or are planning to change the world with your ideas (and a bit of number crunching), join us!

We meet each month to present an inspiring talk or organize a data-hacking session.
