Overview

Backend for Ethiopia’s first online cinema. Thousands of users on Android and iOS relied on rental APIs, time-limited access, mobile authentication, and payment gateway integrations.

Design notes

  • Rentals were server-authoritative, so the client never decided when access expired.
  • Payment flow was idempotent, so a retried payment never created a duplicate rental.
