• Design the new architecture using FastAPI + Pydantic
• Implement endpoints for authentication, dataset management, and annotations
• Set up CORS, security, and rate limiting
• Write unit and integration tests

Deliverables

• Full backend codebase in FastAPI
• Complete API documentation (Swagger)
• Dockerfile and setup scripts
• Testing suite and test coverage report
