Project: Tenant Management: An Evolutionary Project
Current Evolution: Modular Architecture
Evolution Focus: Code organization and separation of concerns
Status: ✅ Complete
Evolution 2: Modular Architecture
Evolution Overview
The second evolution focused on clean architecture and separation of concerns. This modular monolith approach taught the importance of organized code structure while maintaining the benefits of a single deployable unit.
Key Learning Objectives
- Modular Architecture: Breaking down the single file into organized modules
- Service Layer Pattern: Implementing business logic separation
- API Design: Creating RESTful APIs with proper HTTP methods
- Frontend-Backend Separation: React frontend with Python backend
- Clean Code Principles: Writing maintainable, testable code

Evolution Outcomes
This evolution successfully transformed the single-file application into a well-structured modular monolith. It demonstrated the importance of clean architecture while maintaining the benefits of a single deployable unit.
The modular approach provided a solid foundation for understanding enterprise patterns and prepared the codebase for the next evolution into Java/Spring Boot.
