Ticket purchase service with safe concurrency and idempotent retries
It solves the classic problem of overselling tickets by enforcing atomic seat allocation and idempotent request handling. The app uses PostgreSQL transactions and middleware to guarantee that each seat is sold once, even under heavy parallel load. Designed for event organizers or developers building ticketing platforms who need a ready‑made, testable backend. Compared to generic examples, it ships with concurrency tests and clear Docker setup, making deployment straightforward.
