Flutter Developer Needed — Configure, Build & Submit Completed App to App Store and Google Play
Description:
I have a fully written, complete Flutter codebase for a real-time baseball prediction app called UB the Pitcher. Every line of code is already written. I need a skilled Flutter developer to configure it with my credentials, build it, test it, and submit it to both the Apple App Store and Google Play Store.
This is not a coding job. You are not writing anything. The code is done.
Your role is purely technical configuration, testing, and store submission.
About the app:
UB the Pitcher is a real-time MLB pitch prediction game. Users predict pitch outcomes during live games and earn points. The app includes live scoring, leaderboards, user profiles, in-app subscriptions, ads, and a multiplayer challenge room system.
Everything already done:
Complete Flutter codebase fully written and ready to hand over
All screens, logic, scoring, and data connections coded
Firebase project created
AdMob account created
RevenueCat account created
Railway relay server live and receiving real-time Sportradar game data
Your job is:
Set up Flutter development environment
Configure app with my API keys and credentials
Run on iOS and Android simulators and confirm everything works
Connect and verify live WebSocket data feed during a real MLB game
Test on real physical devices
Set up TestFlight for iOS beta
Set up Google Play Internal Testing Track for Android
Fix any environment-specific issues that arise
Submit to Apple App Store
Submit to Google Play Store
Stay on the job until both stores approve the app
Hard requirements:
Must own a Mac — non-negotiable for iOS builds
Must have previously submitted Flutter apps to both App Store and Google Play
Proven Firebase and WebSocket experience in Flutter
RevenueCat or equivalent subscription integration experience
Daily communication and updates during active work
