I will fix react native expo mvp app react native firebase lovable pwa web app to app

It runs perfectly in Expo Go. You build it, hand it to a real device, and it crashes on the splash screen. No error that makes sense, no warning, nothing you did differently.

Expo builds fail for reasons that never show up in dev: dependency mismatches, native module conflicts, memory errors during the build itself. Push notifications make it worse, working fine on Android while silently doing nothing on iOS, or vice versa, with no clear reason why. Almost everyone hits this. Almost nobody gets a straight answer.

I go into your project, isolate the exact dependency, config, or native module causing the build to fail, fix it, and rerun the build until it completes clean. If Firebase Cloud Messaging is involved, I verify it's actually delivering notifications on both iOS and Android, not just configured to look like it should.

You get a working build, a short explanation of what was actually broken (not just "it's fixed now"), and notifications that reliably reach your users.

Send me your Expo project and the exact error log. I'll tell you what's actually wrong before I touch anything.
