What it does
- Structured Knowledge Base
- Topics organised by domain — system design, DSA, design patterns, AI/ML — each a Markdown file with YAML frontmatter for difficulty, tags and tracking.
- Automated Daily Emails
- A GitHub Actions cron job picks a topic at random and sends it as a revision email.
- Self-Updating Metadata
- After sending, the job writes back to the source file, updating last_sent and incrementing review_count.
- Difficulty-Based Selection
- Easy/medium/hard tags allow weighted or filtered selection as the base grows.
- Git-Native Tracking
- Revision history lives in git commits. No external database.
