Jakub Kasprzyk

hey, I'm Jakub 👋

I'm a 20-year-old Mobile Software Engineer based in Kraków, building cross-platform apps with React Native and Expo. Currently at GMI software, where I also work on our open-source native modules — react-native-better-maps and react-native-better-clustering.

Previously at App Magic shipping TapNote, at Software Mansion contributing to Radon IDE, and three years at MyMusic working on MUGO and JustWin.

On the side I'm building Łatwa Ustna, an AI tutor that helps Polish students prepare for the written and oral matura exam.
