I started giving public and mostly IT-related talks in 2016. Until now (April 2020) I delivered over 75 talks in various formats, from Pecha Kucha (20 slides x 20 seconds each) to Deep Dive (2,5h long). I spoke in Poland and Europe, both small community events, both huge cinema rooms. Many of my talks (but not all of them) have both English and Polish versions. Some have been given many times, some just once, some were given awards, and all were made with passion.
I’ve attended as a speaker several conferences and Java User Groups, including: 4Developers Festival, BoilingFrogs, ChamberConf, CodeCamp Romania, CodeMotion Milan, CodeMotion Spain, CoffeeJUG Lviv, Devoxx Belgium, Devoxx Poland, Devoxx Ukraine, GDG DevFest Toulouse, GDG DevFest Wroclaw, GeeCON Poland, GreenField Conf, Java Developer Days, JavaDays Lviv, JAVIPS, jLove, JPoint Russia, ScalaLove, SegFault (& CoreDump), SilesiaJUG, SpreadIT, VirtualJUG, WarszawaJUG, WroclawJUG and others.
