Full-Stack Flutter App Development

I need an experienced Flutter developer who can take my concept from wireframes to a polished, store-ready release on both iOS and Android. The app’s purpose is unique to my business (not a standard e-commerce, social, or productivity tool), so its core features will be discussed in detail once an NDA is in place.

What is already clear:

• Cross-platform build in Flutter/Dart
• End-to-end stack: UI, state management, secure API layer, database, and cloud deployment
• Native Biometric Authentication (Face ID, Touch ID, Android equivalents) baked into the login flow
• Store compliance, testing, and submission for App Store & Google Play

Deliverables:

1. Full source code in a private Git repository
2. Working staging builds for iOS (.ipa) and Android (.apk/.aab)
3. Production-ready backend (Firebase, Supabase, or similar—happy to discuss) with documented endpoints
4. Release builds accepted by both stores

Acceptance criteria: smooth biometric sign-in on real devices, zero critical bugs in QA, and successful store approval.

If you have a portfolio of Flutter apps with biometric login already in market, that will help us hit the ground running.
