Expo at scale in fast paced startup; Build, Deploy, Publish
summary
Company runs two apps with a three-engineer team using Expo and EAS and maintains a single JS codebase instead of separate native projects. CI/CD uses EAS Build and EAS Submit with GitHub Actions to produce signed binaries and auto-upload to stores. Over‑the‑air EAS Update lets fixes publish in seconds so users get bug fixes before App Store approval (which can take two days). Expo provides camera, file system, location and push APIs and removes most native build complexity.
