EarlyEco Backend is a FastAPI service for participatory health intelligence, built to collect frequent user health check-ins, assess individual risk, and generate actionable insights at both user and community levels. The system supports authentication, session management, health trend tracking, warning/suggestion generation, community-location risk summaries, and synthetic data generation for demo/testing workflows.
