I had an hour to kill. Built my first Java project.

Never written Java before. Needed it for a client job.

Backstory: I was mid-session building English Pro when my Claude quota reset timer kicked in. Had exactly ~1 hour before it came back. Needed something to do.
Turns out an hour is enough to learn a new language.

74 minutes later:
✅ Spring Boot from scratch
✅ Multi-tier prize pools
✅ Dynamic weight algorithm
✅ Loss streak protection
✅ 80-level pet bonus system
✅ Item system
✅ Timer sessions
✅ Monte Carlo simulation (100k runs, 3.5% margin ✅)
✅ Swagger docs

Client went with someone else.
Kept the case study.
Not a bad trade.
