An AI-powered screening API built with FastAPI that evaluates how well resumes match job descriptions, returning structured analysis including match scores, matched/missing skills, and gap identification. It accepts plain text or PDF resumes, caches results with SHA-256 hashing to avoid redundant LLM calls, and persists analyses in PostgreSQL as JSONB. The architecture uses a swappable LLM provider interface with JSON validation, retry logic, and input truncation for defensive handling of model output.
