Speaker bio

I’m a software developer, currently working at Pragmatic Coders in Krakow, PL. While mostly using Python as my language of choice, I sometimes write a little bit of JavaScript and Solidity. I also know a thing or two about Amazon Web Services.

In addition to that, I’m co-organising meetups of Pykonik, Krakow Python User Group.

I already had a chance to give this talk on 4Developers conference in Poland, on Pykonik (https://www.meetup.com/Pykonik/) and will be presenting it on upcoming PyWaw meetup (http://pywaw.org/) as well as PyData Warsaw conference (https://pydata.org/warsaw2017/).
