Clean Architecture + MVVM
UI → ViewModel → UseCase → Repository → DataSource
✔ Scalable ✔ Testable ✔ Production Ready ✔ Modular
Most developers struggle with DSA because they don't know:
- what to solve
- what pattern to learn
- whether their solution is optimal
LeetFlow solves this using AI-powered guidance.
- Progress analytics dashboard
- Cloud backup & sync
- Leaderboard
- Study groups
- Interview simulation mode
- Spaced repetition for flashcards
