About Stefan
I fell in love with Frontend development ten years ago, and since the beginning, I learn in public. Sharing my everyday web development discoveries while drinking coffee in bed is my favorite Sunday morning activity.
Whenever I read something and think "Huh! I didn't know that!", I write it down. This approach has led to 645 articles on this blog so far.
