My first app was thousands of lines in one class

Confession: During my first internship in 2012, I built my very first app: a material management desktop app in Java Swing.

Thousands of lines of code… all in one class, inside one constructor. Yes — logic, UI, DB ops. All in one place.

I opened and closed a JDBC connection for every database operation. Spaghetti code would’ve looked clean next to that mess 😂

But hey — it was functional. I shipped it. Presented it. And got a great grade 😎

... and Guess what? I even uploaded the soutenance to YouTube… It now has 114K+ views and multiple kind comments from students who found it helpful.
