I’m preparing for an upcoming conference and need a lightweight mobile app whose core job is to keep attendees instantly informed. The moment a room changes, a keynote starts early, or a sponsor announces a giveaway, the app must ping everyone’s phone with a clear push notification. Because our audience is split almost evenly between iOS and Android users, I need native builds—or a solid cross-platform solution—that ship to both App Store and Google Play on the same timeline. A simple, scrollable feed for recent announcements will back up the notifications so latecomers can catch up quickly. I already maintain a real-time JSON endpoint with all conference updates; the app just has to consume that feed securely, cache lightly for offline viewing, and respect both dark and light modes. To keep the project moving fast, I only want to see past work that demonstrates you’ve shipped production apps with a similar push-notification workflow. A short link list or TestFlight/Play Test invite is perfect—no sprawling proposals needed. Deliverables I need from you: • Source code and build scripts • Test builds for iOS and Android with working push alerts • Store-ready release packages (IPA & AAB) plus step-by-step deployment notes If you’ve handled real-time updates at scale before, this should be a quick win for both of us.
