The first AHA moment striked me when I was around 11 years old. This was the first time I ever been introduced into programming.

I've started playing around with visual basic on my own and aha moment striked when I realised I can make programs to solve math problems... But that was just a lightbulb....

The overall AHA moment happened when I had the knowledge to do so and actually started implementing text book solutions in the app and passing few values from tasks and... Results were great!

From that point I went on with programs as my math problem solver in most of my cases. This not only helped me to save time but actually writing the program helped me to get better at math.

Dev badass moments: every time that lightbulb moment hits when building or debugging difficult things.

Spent 2 weeks of hardly coding a project to then figure out a nice data structure that fixed all my issues and difficulties. It was definitely a good day.
