I already have a FastAPI-based REST backend for a Task & Event Management system, but several endpoints still need polish—especially around request and response validation. Your mission is to review the current CRUD routes, spot any weak validation patterns, and refactor where necessary so the API consistently returns the right status codes, clear error messages, and strongly-typed payloads. You will receive the existing repo and the full endpoint spec as soon as we start. I expect clean, well-commented code that follows FastAPI and Pydantic best practices, keeps the project structure maintainable, and doesn’t break the current functionality. Deliverables • Endpoint audit report highlighting validation gaps • Refactored FastAPI routes with improved Pydantic models and error handling • Any new utility functions or middleware required to keep responses uniform • Brief setup notes or README updates so the next developer can hit the ground running If you’ve tightened up FastAPI projects before and can communicate progress clearly over the next couple of weeks, let’s talk.
