Looking for Flutter Developer to Build a Dating App

I'm looking for an experienced Flutter developer to build a dating app for iOS and Android. The app will include user registration, profiles, matching, chat, subscriptions, push notifications, and location-based features. I'm looking for someone who has experience building and launching real mobile applications, preferably social, dating, or messaging products. The backend is planned around Firebase, so experience with Firebase Auth, Firestore, Cloud Functions, and push notifications is important. I'd also like someone who can help make technical decisions, suggest the right architecture, and build a scalable product rather than simply implement screens. Please share examples of Flutter apps you've worked on, your role in those projects, and any experience you have with chat, subscriptions, or social networking applications.
