I opened my Twitter account more than 13 years ago, in August 2009. For 12 years, I kept focusing on professional-related content: Java, the JVM, programming, etc. I built my audience, trying to promote good technical content, either my own or stuff that I enjoyed reading.
Then, on February 24th, Russia invaded Ukraine. My first visit to Ukraine was in 2014, just after the Maidan revolution. During eight years, I returned there often and made plenty of friends.
