I wrote my first Android app back in 2011 and never really stopped. Some apps I grew from nothing to millions of users, others already had millions when I showed up and I got to make them better.
I'm free now and looking for an Android lead or senior role, remote or around Katowice, Kraków or Wrocław. Email me, or find me on LinkedIn and GitHub.
