Dojolom
Dojolom profiles how someone learns, then delivers short daily sessions that mix review, format-matched teaching, mini-games, and quick checks. A Leitner spaced-repetition engine and a behaviour log adapt the format and review timing over time. It is a static Next.js app with unit and end-to-end tests.

Learner profile from five onboarding scenarios
Leitner spaced repetition at 1, 2, 4, 7, 15, and 30 days
Fully static, tested with Vitest and Playwright
Overview
Most learning apps teach everyone the same way. Dojolom starts by working out how a learner prefers to take things in, then shapes every session around that, while spaced repetition makes sure what was learned comes back at the right time.
What I built
A static-exported Next.js app with no backend; progress lives on the device. The session engine sequences review, teaching, play, and checks, the spaced-repetition scheduler decides what returns and when, and a content validator keeps lesson units consistent. Unit tests cover the learning logic and Playwright covers a full study session.
