10 unique formats nobody else teaches
100 lessons across 10 themed modules: Code Detective (broken-codebase mysteries), AI Pair-Reversed (catch Claude's deliberate bugs), Time-Travel Refactor (Python 2.4 → modern), Bug Bounty, Code Golf (shortest wins), Refactor Master (legacy → idiomatic), Whodunit Mysteries, Performance Showdowns, Edge Case Hunter, Magic Demystified (dunders, descriptors, metaclasses, full mini-ORM).
Lesson formats nobody else teaches — Code Detective (broken-codebase mysteries), AI Pair-Reversed (catch Claude's deliberate bugs), Time-Travel Refactor (Python 2.4 → modern), Bug Bounty, Code Golf, Refactor Master.
Mostly mid-level. You need to read code fluently. Foundations + a couple of the advanced tracks first, then come here for the variety.
Because LeetCode-style drill burns out. This track is the variety that keeps you coming back — same Python skills, different game.
The Refactor Master + Bug Bounty modules give you concrete improved-code-by-X bullets. Code Golf is mostly fun, not portfolio material.
All 100 lessons unlock for $12/month or $89/year. 7-day free trial — card required, cancel in 1 click anytime in Settings.
