I'm Phoebus Chang — 15, and I've been building real software since I was 13. Not tutorials. Things with users, things that made money.

Right now I'm CEO of Pretimed, a startup that fixes plan fizzle — when group-chat hype dies and nobody ends up going. I wrote the entire backend myself. 10k+ lines of Python/FastAPI. I recruited and lead a team of five.

Before that: sold a scheduling app to a local climbing gym for $300. Built QuizGen — $85 in organic revenue, zero marketing. Started Phoebus HQ on YouTube, 400+ subscribers explaining CS without the filler.

I do competitive programming, study neural networks from the math up, and stay on top of AP Physics and Calculus simultaneously.

I don't wait until I'm ready. I figure it out while doing it.
