Featured project

chinese.io on mobile: dashboard showing cards due for review, the day streak and HSK progress

2026 · SaaS · Solo project

The need

Review vocabulary at the right moment and know where you stand on the HSK scale, without juggling several tools.

What I built

Spaced-repetition reviews, an adaptive placement test, HSK progress tracking with a daily streak, and Stripe subscriptions.

Technical choices

  • Next.js (React Server Components), PostgreSQL, Better Auth
  • FSRS algorithm (ts-fsrs) to schedule every review
  • Hosted in Europe with GDPR in mind, billing through Stripe
