Fix React Native CLI Build Issues + Design Feedback + iOS/Android Deployment

I have an existing React Native CLI app (not Expo) that needs the following: Part 1 : Build Fixes: - Fix build errors on [iOS/Android/both] - Update [specific library/dependency] to latest compatible version - Resolve [specific issue, e.g., native module linking, gradle version conflict] Part 2 : Design Brainstorm: - Review the app's current UI/UX and flag major design issues - Suggest improvements for [specific areas, e.g., navigation, onboarding, key screens] - Deliverable: short written notes or annotated screenshots (not full redesign) Part 3 : Deployment: - Deploy app to Apple App Store and Google Play Store - Handle signing, provisioning profiles, and store listing setup - I will provide developer account access (Apple Developer + Google Play Console) Scope: - App repo will be shared via GitHub (private repo, NDA available) - Deliverable: working build + design feedback notes + app live/submitted on both stores Requirements: - 4+ years React Native CLI experience (not just Expo) - Experience with native iOS/Android build tooling (Xcode, Gradle) - Experience with App Store and Play Store submission process - Some UI/UX sensibility, ability to spot and articulate design problems Please include: similar project you've deployed, and your estimated turnaround time.
