🎯 Modular Monolith Benefits

✅ Advantages

• Clear Boundaries: Each domain has its own router and service layer
• Easy Testing: Modules can be tested independently
• Simple Deployment: Single application, no orchestration needed
• Shared Resources: Efficient database connection pooling
• Gradual Migration: Can extract to microservices later if needed
