About CleanKata
CleanKata started from a simple frustration: most tutorials teach you how to make something work — rarely why it should be structured that way.
This matters more than ever now that AI tools write code daily — but functional isn't the same as maintainable. Knowing clean practices lets you guide AI to better output, spot its shortcuts, and refactor with confidence. CleanKata builds those skills with self-contained micro-lessons in Python or TypeScript — 5 to 12 minutes each.
