At 11, I fell for one simple fact: a perfectly logical machine would do exactly what I told it to. Now machines think for themselves. That still blows my mind.
Since then, I've kept building whatever my own life was missing: timetable apps for my high school, an online judge for my classmates, and a reservation system for my college's club rooms. Most recently, I rebuilt the backend behind a job platform.
