At the event, you will meet employers and service providers from the IT / data science field, who will directly introduce you to the profiles of their organisations and talk about their offers.


Since 2005, we have been supporting the Polish IT / data science community in its development. We are not only the organizer, but also the initiator of many significant events aimed at industry professionals and students, such as Warsaw IT Days, Data Science Summit, The Hack Summit, DevAI by DSS, MS Tech Summit, IT Job Fair and many meetups. We also help organize IT and data science conferences to companies / organizations interested in such activities. For, questions, feel free to contact us.
PyData Warsaw is a group for anyone interested in Machine Learning and Artificial Intelligence and their applications such as Big Data, predictive analytics, data science and robotics. Our main focus is Python based technology stack, but not only. All skill levels are welcome. We started this group because we want to meet other enthusiasts in the area. We're looking forward to exploring exciting new ideas with everybody!
PyWaw is a community that brings together Python enthusiasts from Warsaw and beyond. Our group welcomes not only Computer Science students and professional developers but also anyone who has just begun their Python journey. Our goals are diverse - sharing experiences and ideas, connecting Python enthusiasts in Warsaw, and promoting Python as a versatile programming language. Join us anytime!
