    I am an expert in creating cross-platform mobile apps using Flutter. I have a lot of experience with full cycle Flutter develop. Also with TDD projects with 100% test coverage. And good BA understanding. While I have a strong knowledge of basics, such as common design patterns (BLoC, Provider, ScopedModel), programming languages (Dart, Java, TypeScript) and standard mobile solutions (In-App Purchases, Maps, Camera, Push Notifications, Apple Pay etc.), I also have a great experience in wide number of third-party SDKs: Facebook, Stripe, Google Maps, ad networks etc. My backend experience is in Google Firebase. Using Google Cloud Firestore as a database and Firebase Cloud Functions written on TypeScript I can easily create a robust backend for mobile and web apps. In 2019 I started to move to cross-platform development using Flutter/Dart. I also contribute to Flutter project itself in my spare time.
