Adventures in FastAPI: A Choose-Your-Own PyCon AU Talk
summary
Live demo shows a FastAPI backend powering a choose‑your‑own slide deck with a React frontend, Postgres + SQLAlchemy for data, and real‑time voting over web sockets. Reliability depends on a cloud scaling mismatch so the fix is a centralized pub/sub service (used: Azure Web Pub‑Sub). Pydantic handles request and response validation and automatic docs. 91 unique voters and ~170 votes are recorded; parts of the real‑time path fail intermittently but core features and source code exist.
