Mosaic is a Kotlin framework that transforms backend development through composable tiles that automatically handle caching, concurrency, and dependency resolution. Why this matters: In a traditional API with 20+ services, you'd need to mock databases, HTTP clients, message queues, and coordinate complex test data. 🎯 Response-First: Think from the response up, not database down ⚡ Zero Duplication: Intelligent caching eliminates redundant fetches 🔄 Automatic Concurrency: Parallel execution without complexity 🧩 Type Safety: Compile-time guarantees for all dependencies 🧪 Natural Testability: Mock any tile, test in isolation 📦 Production Ready: Handles errors, edge cases, and performance optimization
