🧠 System Architecture Overview User → API Layer → Workflow Engine → Job Queue → Worker Executors → External Integrations ↓ Database Key Components:
API Layer – Handles authentication, workflow CRUD, execution triggers
Workflow Engine – Parses nodes and executes them sequentially or conditionally
Queue System – Manages async background execution
Workers – Executes nodes safely with retry & failure control
SaaS Layer – Enforces subscription rules and usage limits
🔐 Security & Resiliency
Secure coding practices
JWT-based authentication
Input validation & sanitization
Rate limiting
Retry policies for failed jobs
Structured error logging
Isolation between tenants
