Challenge
AI tools write most of the boilerplate now, and many senior engineers notice they can no longer write a Spring Boot or FastAPI service from memory, which hurts in interviews and offline work.
What we built
We built CodeMuscle: professional reference code sits next to an IDE-style editor, the user retypes it by hand, and the app compares every keystroke in real time. Progress statistics, recommendations and achievements keep practice going, drafts sync across devices, and no code is ever sent to AI.
Highlights
- IDE-style Monaco editor beside professional reference projects
- Real-time comparison while typing, language-aware completion
- Java 21 / Spring Boot and Python / FastAPI practice projects
- Progress metrics, recommendations and achievements
- Multi-device drafts, secure sessions and encrypted backups
