Fun fact: My first talk as a #JavaChampion was at @GeeCON Prague. 🥰
At #geecon, the amazing @maritvandijk.bsky.social, Java Champion and Developer Advocate at @jetbrains.com, will share an important insight: we spend more time reading code than writing it. Ready to level up your code-reading game and master those plot twists? 2025.geecon.org/speakers/inf...
