Flutter Developer Needed | Firebase, MoEngage, UI Updates & Store Submission

I need an experienced Flutter developer to update my existing production app and submit new builds to Google Play, TestFlight, and the App Store within two days of project start. The work covers four areas: Push notifications: Configure Firebase Cloud Messaging for Android and iOS, including notification handling and on-tap navigation to the correct screens. Analytics: Integrate MoEngage and track a Feature Usage event when specified core features are opened or completed. Events should include consistent properties that our marketing team can use for segmentation. UI updates: Make a few colour scheme and layout changes based on the Figma references and screen checklist I’ll provide. Release: Build and test on real Android and iOS devices, then upload the updated versions to Google Play, TestFlight, and the App Store. I can provide review screenshots if needed. The Git repository, signing credentials, Figma references, and change checklist are ready to share with the selected developer. Please communicate clearly, flag blockers early, and help address store feedback through final approval. The two-day deadline applies to completing the work and submitting the builds; store review timing may vary. Budget: ₹2,000 INR Timeline: 2 days from project start Note: Only developers based in India should apply. Please share links to Flutter apps where you’ve handled push notifications, analytics, or store releases, and confirm exactly when you can start.
