FlowShield: Temporal.io AI-Enhanced Authentication System
Production-ready authentication system combining Temporal.io workflows with AI-powered fraud detection. Features JWT tokens, email verification, password reset flows, and intelligent security analysis using local AI models with graceful fallbacks.
🔐 Real-World Temporal Authentication with AI Enhancement
FlowShield demonstrates a production-ready authentication system that combines Temporal.io workflows with AI-powered security features. Unlike typical demo projects, this system handles real-world constraints like sandbox restrictions while providing immediate value through hybrid architecture patterns.
🚀 What Makes This Different
Pragmatic Hybrid Architecture: Instead of forcing "pure Temporal" patterns, this system gracefully falls back to direct database operations when workflows encounter issues, ensuring 100% uptime while demonstrating proper Temporal integration patterns.
AI-Enhanced Security: Features real-time fraud detection, intelligent password analysis, and behavioral authentication using local AI models (Ollama) with fallbacks to rule-based systems.
🛠️ Complete Working System
