DynamiCode

A spaced repetition platform designed to help developers master data structures and algorithms through scientifically-backed study scheduling.

Key Features

• Spaced Repetition Algorithm — Adaptive scheduling that optimizes review intervals based on performance
• Calendar Heatmaps — Visual progress tracking inspired by GitHub contribution graphs
• Multi-repo Architecture — Frontend, backend, and shared packages across 3 repositories
• Comprehensive E2E Testing — Full Playwright test coverage across the entire platform

Some Code

1
// Example of spaced repetition scheduling logic
2
function calculateNextReview(lastInterval: number, performance: "easy" | "good" | "hard"): number {
3
  const performanceFactor = {
4
    easy: 2.5,
5
    good: 1.5,
6
    hard: 0.5,
7
  }[performance];
8
  return Math.ceil(lastInterval * performanceFactor);
9
}
